# `PhiaUi.Components.MonthPicker`
[🔗](https://github.com/charlenopires/PhiaUI/blob/v0.1.17/lib/phia_ui/components/calendar/month_picker.ex#L1)

Month selection input — styled native `<input type="month">`.

Wraps the browser's native month picker with PhiaUI's input styling (borders,
focus ring, size variants, error state). Supports standalone use or
Phoenix form field integration with changeset error display.

Value format: `"YYYY-MM"` (e.g. `"2026-03"`).

Zero JavaScript — uses the native browser month control.

## Examples

    <%!-- Standalone --%>
    <.month_picker id="period" name="billing_month" label="Billing Month" value="2026-03" />

    <%!-- With min/max constraints --%>
    <.month_picker id="period" name="billing_month" min="2024-01" max="2026-12" />

    <%!-- Form field integration --%>
    <.month_picker
      id="subscription_month"
      name={@form[:month].name}
      value={@form[:month].value}
      errors={Enum.map(@form[:month].errors, &translate_error/1)}
      label="Subscription Month"
    />
