View Source Doggo.Components (Doggo v0.9.1)

This module defines macros that generate customized components.

Usage

Add use Doggo.Components to your module and ensure you also add use Phoenix.Component. Then use the macros in this module to generate the components you need.

use Doggo.Components

When you use Doggo.Components, the module will import Doggo.Components and define a __dog_components__/1 function that returns a map containing the options of the Doggo components you used.

To generate all components with their default options:

Common Options

All component macros support the following options:

  • name - The name of the function of the generated component. Defaults to the macro name.
  • base_class - The base class used on the root element of the component. If not set, a default base class is used.
  • modifiers - A keyword list of modifier attributes. For each item, an attribute with the type :string is added. The options will be passed to Phoenix.Component.attr/3. Most components define a set of default modifiers that can be overridden.
  • class_name_fun - A 2-arity function that takes a modifier attribute name and a value and returns a CSS class name. Defaults to Doggo.modifier_class_name/2.

Some components have additional options that are mostly used to allow the customization of certain class names or to set the Gettext module.

Buttons

Link to this macro

build_button(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a button.

Use this component when you need to perform an action such as submitting a form, confirming an action, deleting an item, toggling a setting, etc.

If you need to navigate to a different page or a specific section on the current page and want to style the link like a button, use button_link/1 instead.

See also button_link/1, toggle_button/1, and disclosure_button/1.

Maturity: Stable

Configuration

Generate the component with default options:

build_button()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :button,
  base_class: "button",
  modifiers: [
    variant: [
      values: ["primary", "secondary", "info", "success", "warning", "danger"],
      default: "primary"
    ],
    size: [values: ["small", "normal", "medium", "large"], default: "normal"],
    fill: [values: ["solid", "outline", "text"], default: "solid"],
    shape: [values: [nil, "circle", "pill"], default: nil]
  ],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage 

<.button>Confirm</.button>

<.button type="submit">
  Submit
</.button>

To indicate a loading state, for example when submitting a form, use the aria-busy attribute:

<.button aria-label="Saving..." aria-busy>
  click me
</.button>

Example CSS

For example CSS, you can have a look at the demo styles.

Link to this macro

build_button_link(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a link (<a>) that has the style of a button.

Use this component when you need to style a link to a different page or a specific section within the same page as a button.

To perform an action on the same page, including toggles and revealing/hiding elements, you should always use a real button instead. See button/1, toggle_button/1, and disclosure_button/1.

Maturity: Stable

Configuration

Generate the component with default options:

build_button_link()

In addition to the common options name, base_class, modifiers, and class_name_fun, the build macro also supports the following options.

  • :disabled_class - This class name is added if the :disabled attribute is set to true.

Default options 

[
  name: :button_link,
  base_class: "button",
  modifiers: [
    variant: [
      values: ["primary", "secondary", "info", "success", "warning", "danger"],
      default: "primary"
    ],
    size: [values: ["small", "normal", "medium", "large"], default: "normal"],
    fill: [values: ["solid", "outline", "text"], default: "solid"],
    shape: [values: [nil, "circle", "pill"], default: nil]
  ],
  class_name_fun: &Doggo.modifier_class_name/2,
  disabled_class: "is-disabled"
]

Usage 

<.button_link patch={~p"/confirm"}>
  Confirm
</.button_link>

<.button_link navigate={~p"/registration"}>
  Registration
</.button_link>

Example CSS

For example CSS, you can have a look at the demo styles.

build_disclosure_button(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a button that toggles the visibility of another element.

Use this component to reveal or hide additional content, such as in collapsible sections or dropdown menus.

For a button that toggles other states, use toggle_button/1 instead. See also button/1 and button_link/1.

Maturity: Refining

Configuration

Generate the component with default options:

build_disclosure_button()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :disclosure_button,
  base_class: "button",
  modifiers: [
    variant: [
      values: ["primary", "secondary", "info", "success", "warning", "danger"],
      default: "primary"
    ]
  ],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage

Set the controls attribute to the DOM ID of the element that you want to toggle with the button.

The initial state is hidden. Do not forget to add the hidden attribute to the toggled element. Otherwise, visibility of the element will not align with the aria-expanded attribute of the button.

<.disclosure_button controls="data-table">
  Data Table
</.disclosure_button>

<table id="data-table" hidden></table>

CSS

To select disclosure buttons without class names and to apply styles depending on the state (e.g. to render a caret), you can use the aria-controls and aria-expanded attributes.

button[aria-controls][aria-expanded] {
  /* Base styles for disclosure buttons */
}

button[aria-controls][aria-expanded="true"] {
  /* Styles when content is visible */
}

Example CSS

For example CSS, you can have a look at the demo styles.

Link to this macro

build_switch(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a switch as a button.

If you want to render a switch as part of a form, use the input/1 component with the type "switch" instead.

Note that this component only renders a button with a label, a state, and <span> with the class switch-control. You will need to style the switch control span with CSS in order to give it the appearance of a switch.

Maturity: Experimental

Configuration

Generate the component with default options:

build_switch()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :switch,
  base_class: "switch",
  modifiers: [],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage 

<.switch
  label="Subscribe"
  checked={true}
  phx-click="toggle-subscription"
/>
Link to this macro

build_toggle_button(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a button that toggles a state.

Use this component to switch a feature or setting on or off, for example to toggle dark mode or mute/unmute sound.

See also button/1, button_link/1, and disclosure_button/1.

Maturity: Developing

Configuration

Generate the component with default options:

build_toggle_button()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :toggle_button,
  base_class: "button",
  modifiers: [
    variant: [
      values: ["primary", "secondary", "info", "success", "warning", "danger"],
      default: "primary"
    ],
    size: [values: ["small", "normal", "medium", "large"], default: "normal"],
    fill: [values: ["solid", "outline", "text"], default: "solid"],
    shape: [values: [nil, "circle", "pill"], default: nil]
  ],

]

Usage

With a Phoenix.LiveView.JS command:

<.toggle_button on_click={JS.push("toggle-mute")} pressed={@muted}>
  Mute
</.toggle_button>

Accessibility

The button state is conveyed via the aria-pressed attribute and the button styling. The button text should not change depending on the state. You may however include an icon that changes depending on the state.

CSS

A toggle button can be identified with an attribute selector for the aria-pressed attribute.

// any toggle button regardless of state
button[aria-pressed] {}

// unpressed toggle buttons
button[aria-pressed="false"] {}

// pressed toggle buttons
button[aria-pressed="true"] {}

build_date(opts \\ [])

View Source (since 0.6.0) (macro)

Formats a Date, DateTime, or NaiveDateTime as a date and renders it in a <time> element.

Maturity: Refining

The API of this component can be considered fairly stable, but there are still uncertainties about accessibility aspects, such as the handling of the <time> element and its datetime attribute by screen readers and the limited accessibility of the title attribute.

Configuration

Generate the component with default options:

build_date()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :date,
  base_class: nil,
  modifiers: [],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage

By default, the given value is formatted for display with to_string/1. This:

<.date value={~D[2023-02-05]} />

Will be rendered as:

<time datetime="2023-02-05">
  2023-02-05
</time>

You can also pass a custom formatter function. For example, if you are using ex_cldr_dates_times in your application, you could do this:

<.date
  value={~D[2023-02-05]}
  formatter={&MyApp.Cldr.Date.to_string!/1}
/>

Which, depending on your locale, may be rendered as:

<time datetime="2023-02-05">
  Feb 2, 2023
</time>

If you pass a title_formatter, a title attribute is added to the element. This can be useful if you want to render the value in a shortened or relative format, but still give the user access to the complete value. Note that the title attribute is only be accessible to users who use a pointer device. Some screen readers may however announce the datetime attribute that is always added.

<.date
  value={@date}
  formatter={&relative_date/1}
  title_formatter={&MyApp.Cldr.Date.to_string!/1}
/>

Finally, the component can shift a DateTime to a different time zone before converting it to a date:

<.date
  value={~U[2023-02-05 23:22:05Z]}
  timezone="Asia/Tokyo"
/>

Which would be rendered as:

<time datetime="2023-02-06">
  2023-02-06
</time>

]

Usage

By default, the given value is formatted for display with to_string/1. This:

<.datetime value={~U[2023-02-05 12:22:06.003Z]} />

Will be rendered as:

<time datetime="2023-02-05T12:22:06.003Z">
  2023-02-05 12:22:06.003Z
</time>

You can also pass a custom formatter function. For example, if you are using ex_cldr_dates_times in your application, you could do this:

<.datetime
  value={~U[2023-02-05 14:22:06.003Z]}
  formatter={&MyApp.Cldr.DateTime.to_string!/1}
/>

Which, depending on your locale, may be rendered as:

<time datetime="2023-02-05T14:22:06.003Z">
  Feb 2, 2023, 14:22:06 PM
</time>

The component can also truncate the value before passing it to the formatter.

<.datetime
  value={~U[2023-02-05 12:22:06.003Z]}
  precision={:minute}
/>

If you pass a title_formatter, a title attribute is added to the element. This can be useful if you want to render the value in a shortened or relative format, but still give the user access to the complete value. Note that the title attribute is only be accessible to users who use a pointer device. Some screen readers may however announce the datetime attribute that is always added.

<.fallback value={@some_value} />

Apply a formatter function to @some_value if it is not nil:

<.fallback value={@some_value} formatter={&format_date/1} />

Set a custom placeholder and text for screen readers:

<.fallback
  value={@some_value}
  placeholder="n/a"
  accessibility_text="not available"
/>

build_time(opts \\ [])

View Source (since 0.6.0) (macro)

Formats a Time, DateTime, or NaiveDateTime as a time and renders it in a <time> element.

Maturity: Refining

The API of this component can be considered fairly stable, but there are still uncertainties about accessibility aspects, such as the handling of the <time> element and its datetime attribute by screen readers and the limited accessibility of the title attribute.

Configuration

Generate the component with default options:

build_time()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :time,
  base_class: nil,
  modifiers: [],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage

By default, the given value is formatted for display with to_string/1. This:

<.time value={~T[12:22:06.003Z]} />

Will be rendered as:

<time datetime="12:22:06.003">
  12:22:06.003
</time>

You can also pass a custom formatter function. For example, if you are using ex_cldr_dates_times in your application, you could do this:

<.time
  value={~T[12:22:06.003]}
  formatter={&MyApp.Cldr.Time.to_string!/1}
/>

Which, depending on your locale, may be rendered as:

<time datetime="14:22:06.003">
  14:22:06 PM
</time>

The component can also truncate the value before passing it to the formatter.

<.time
  value={~U[2023-02-05 12:22:06.003Z]}
  precision={:minute}
/>

If you pass a title_formatter, a title attribute is added to the element. This can be useful if you want to render the value in a shortened or relative format, but still give the user access to the complete value. Note that the title attribute is only be accessible to users who use a pointer device. Some screen readers may however announce the datetime attribute that is always added.

<.time
  value={@time}
  formatter={&relative_time/1}
  title_formatter={&MyApp.Cldr.Time.to_string!/1}
/>

Finally, the component can shift a DateTime to a different time zone:

<.time
  value={~U[2023-02-05 23:22:05Z]}
  timezone="Asia/Tokyo"
/>

Which would be rendered as:

<time datetime="08:22:05">
  08:22:05
</time>

Feedback

Form

Link to this macro

build_field(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a form field including input, label, errors, and description.

A Phoenix.HTML.FormField may be passed as argument, which is used to retrieve the input name, id, and values. Otherwise all attributes may be passed explicitly.

Maturity: Developing

Configuration

Generate the component with default options:

build_field()

In addition to the common options name, base_class, modifiers, and class_name_fun, the build macro also supports the following options.

  • :gettext_module - If set, errors are automatically translated using this module. This only works if the :field attribute is set. Without it, errors passed to the component are rendered unchanged.
  • :addon_left_class - This class is added to the input wrapper if the :addon_left slot is used.
  • :addon_right_class - This class is added to the input wrapper if the :addon_right slot is used.
  • :visually_hidden_class - This class is added to labels if :hide_label is set to true.

Default options 

[
  name: :field,
  base_class: "field",
  modifiers: [],
  class_name_fun: &Doggo.modifier_class_name/2,
  gettext_module: nil,
  addon_left_class: "has-addon-left",
  addon_right_class: "has-addon-right",
  visually_hidden_class: "is-visually-hidden"
]

Usage

Types

In addition to all HTML input types, the following type values are also supported:

  • "select"
  • "checkbox-group"
  • "radio-group"
  • "switch"

Class and Global Attribute

Note that the class attribute is applied to the outer container, while the rest global attribute is applied to the <input> element.

Gettext

To translate field errors using Gettext, set the gettext_module option when building the component:

build_field(gettext_module: MyApp.Gettext)

Label positioning

The component does not provide an attribute to modify label positioning directly. Instead, label positioning should be handled with CSS. If your application requires different label positions, such as horizontal and vertical layouts, it is recommended to add a modifier class to the form.

For example, the default style could position labels above inputs. To place labels to the left of the inputs in a horizontal form layout, you can add an is-horizontal class to the form:

<.form class="is-horizontal">
  <!-- inputs -->
</.form>

Then, in your CSS, apply the necessary styles to the .field class within forms having the is-horizontal class:

form.is-horizontal .field {
  // styles to position label left of the input
}

The component has a hide_label attribute to visually hide labels while still making them accessible to screen readers. If all labels within a form need to be visually hidden, it may be more convenient to define a .has-visually-hidden-labels modifier class for the <form>.

<.form class="has-visually-hidden-labels">
  <!-- inputs -->
</.form>

Ensure to take checkbox and radio labels into consideration when writing the CSS styles.

Examples 

<.field field={@form[:name]} />
<.field field={@form[:email]} type="email" />

Radio group and checkbox group

The radio-group and checkbox-group types allow you to easily render groups of radio buttons or checkboxes with a single component invocation. The options attribute is required for these types and has the same format as the options for the select type, except that options may not be nested.

<.field
  field={@form[:email]}
  type="checkbox-group"
  label="Cuisine"
  options={[
    {"Mexican", "mexican"},
    {"Japanese", "japanese"},
    {"Libanese", "libanese"}
  ]}
/>

Note that the checkbox-group type renders an additional hidden input with an empty value before the checkboxes. This ensures that a value exists in case all checkboxes are unchecked. Consequently, the resulting list value includes an extra empty string. While Ecto.Changeset.cast/3 filters out empty strings in array fields by default, you may need to handle the additional empty string manual in other contexts.

build_modal(opts \\ [])

View Source (since 0.6.0) (macro)

Renders a modal dialog for content such as forms and informational panels.

This component is appropriate for non-critical interactions. For dialogs requiring immediate user response, such as confirmations or warnings, use .alert_dialog/1 instead.

Maturity: Developing

Configuration

Generate the component with default options:

build_modal()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :modal,
  base_class: "modal",
  modifiers: [],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage

There are two primary ways to manage the display of the modal: via URL state or by setting and removing the open attribute.

With URL

To toggle the modal visibility based on the URL:

  1. Use the :if attribute to conditionally render the modal when a specific live action matches.
  2. Set the on_cancel attribute to patch back to the original URL when the user chooses to close the modal.
  3. Set the open attribute to declare the modal's initial visibility state.

Example

<.modal
  :if={@live_action == :show}
  id="pet-modal"
  on_cancel={JS.patch(~p"/pets")}
  open
>
  <:title>Show pet</:title>
  <p>My pet is called Johnny.</p>
  <:footer>
    <.link phx-click={JS.exec("data-cancel", to: "#pet-modal")}>
      Close
    </.link>
  </:footer>
</.modal>

To open the modal, patch or navigate to the URL associated with the live action.

<.link patch={~p"/pets/#{@id}"}>show</.link>

Without URL

To toggle the modal visibility dynamically with the open attribute:

  1. Omit the open attribute in the template.
  2. Use the show_modal/1 and hide_modal/1 functions to change the visibility.

Example

<.modal id="pet-modal">
  <:title>Show pet</:title>
  <p>My pet is called Johnny.</p>
  <:footer>
    <.link phx-click={JS.exec("data-cancel", to: "#pet-modal")}>
      Close
    </.link>
  </:footer>
</.modal>

To open modal, use the show_modal/1 function.

<.button
  phx-click={Doggo.show_modal("pet-modal")}
  aria-haspopup="dialog"
>
  show
</.button>

CSS

To hide the modal when the open attribute is not set, use the following CSS styles:

dialog.modal:not([open]),
dialog.modal[open="false"] {
  display: none;
}

Semantics

While the showModal() JavaScript function is typically recommended for managing modal dialog semantics, this component utilizes the open attribute to control visibility. This approach is chosen to eliminate the need for library consumers to add additional JavaScript code. To ensure proper modal semantics, the aria-modal attribute is added to the dialog element.

    </button>
  </div>
</.toolbar>

build_tooltip(opts \\ [])

View Source (since 0.6.0) (macro)

Renders content with a tooltip.

There are different ways to render a tooltip. This component renders a <div> with the tooltip role, which is hidden unless the element is hovered on or focused. For example CSS for this kind of tooltip, refer to ARIA: tooltip role.

A simpler alternative for styled text-only tooltips is to use a data attribute and the attr CSS function. Doggo does not provide a component for that kind of tooltip, since it is controlled by attributes only. You can check Pico CSS for an example implementation.

Maturity: Developing

Configuration

Generate the component with default options:

build_tooltip()

The build macro supports the common options name, base_class, modifiers, and class_name_fun.

Default options 

[
  name: :tooltip,
  base_class: "tooltip-container",
  modifiers: [],
  class_name_fun: &Doggo.modifier_class_name/2
]

Usage

With an inline text:

<p>
  Did you know that the
  <.tooltip id="labrador-info">
    Labrador Retriever
    <:tooltip>
      <p><strong>Labrador Retriever</strong></p>
      <p>
        Labradors are known for their friendly nature and excellent
        swimming abilities.
      </p>
    </:tooltip>
  </.tooltip>
  is one of the most popular dog breeds in the world?
</p>

If the inner block contains a link, add the :contains_link attribute:

<p>
  Did you know that the
  <.tooltip id="labrador-info" contains_link>
    <.link navigate={~p"/labradors"}>Labrador Retriever</.link>
    <:tooltip>
      <p><strong>Labrador Retriever</strong></p>
      <p>
        Labradors are known for their friendly nature and excellent
        swimming abilities.
      </p>
    </:tooltip>
  </.tooltip>
  is one of the most popular dog breeds in the world?
