Fields read their errors only under the wire:model name, so a Fortify login form (name="email", no wire:model) never showed "These credentials do not match". Without wire:model they now read the name, turning brackets into dots.

{{-- Choosing from a list: M3's filter chips, or a searchable field with a menu.
|
|
|
|
Two shapes for two jobs, both on `options` (`['id' => …, 'name' => …]`, read through
|
|
`option-value` and `option-label`), `label`, `hint` and `single`:
|
|
|
|
- **Chips**, the default. Every option is on screen and a press turns it on or off — "the days
|
|
you are free" is seven filter chips, not a dropdown opened seven times. `single` makes them
|
|
choice chips, one on at a time.
|
|
- **`searchable`**, for a list too long to lay out — four hundred time zones. A text field
|
|
that filters as you type, with the matches in M3's menu under it: the arrow keys move,
|
|
Enter chooses, Escape puts the field back. One value only. The list is a popover in the top
|
|
layer, placed by CSS anchor positioning, so a card's clipping never cuts it off. `icon`,
|
|
`variant` and `placeholder` are the field's.
|
|
|
|
The selection lives in Alpine, entangled with the `wire:model` property (live with
|
|
`wire:model.live`), rather than in native checkboxes, which would send every value back as a
|
|
string: a list of integers stays a list of integers. Without `wire:model` it works on its own
|
|
and binds with `x-model`. Errors for the property and its items replace the hint. When the
|
|
options change on the server, give the component a `wire:key` that changes with them: the
|
|
options are baked into its Alpine state. --}}
