javascript-hooks

Javascript Hooks

LiveSelect relies on Javascript hooks to work. You need to add LiveSelect's hooks to your live socket.

In your app.js file:

import live_select from "live_select"

// if you don't have any other hooks:
let liveSocket = new LiveSocket("/live", Socket, {params: {_csrf_token: csrfToken}, hooks: live_select})


// if you have other hooks:
const hooks = {
    MyHook: {
      // ...
    },
    ...live_select
}
let liveSocket = new LiveSocket("/live", Socket, {params: {_csrf_token: csrfToken}, hooks})

tailwind-configuration

Tailwind configuration

LiveSelect supports 3 styling modes:

• tailwind: uses standard tailwind utility classes (the default)
• daisyui: uses daisyUI classes.
• none: no styling at all.

The choice of style is controlled by the style option in live_select/3. tailwind and daisyui styles come with sensible defaults which can be selectively extended or completely overridden.

If you're using tailwind or daisyui styles, you need to add one of the following lines to the content section in your tailwind.config.js:

module.exports = {
    content: [
        //...
        '../deps/live_select/lib/live_select/component.*ex' <-- for a standalone app
        '../../../deps/live_select/lib/live_select/component.*ex' <-- for an umbrella app
    ]
    //..
}

Notice the different paths for a standalone or umbrella app.

Refer to the Styling section for further details.

showcase-app

Showcase app

The repository includes a showcase app that you can use to experiment with the different options and parameters for LiveSelect. To start the showcase app, simply run:

mix setup
PORT=4001 mix phx.server

from within the cloned repository. The app will be available at http://localhost:4001. The showcase app allows you to quickly experiment with options and styles, providing an easy way to fine tune your LiveSelect component. The app also shows the messages and events that your LiveView receives. For each event or message, the app shows the function head of the callback that your LiveView needs to implement in order to handle the event.
