livewire-material/resources/views/components/input.blade.php

{{-- A text field: M3's outlined or filled one (resources/views/components/field.blade.php).

     `label`, `hint`, leading `icon`, trailing `icon-right`, `prefix` and `suffix` (text beside the
     value, such as a currency or a unit), `variant`, `size` for unlabelled controls in toolbars,
     and `mono` for a field that holds code. `clearable` adds a trailing button that empties the
     field once it holds something; `copyable` one that copies its value and says so in a snackbar
     (a share link, a token). `counter` counts the characters used against `maxlength`, at the end of
     the supporting-text row; `full` lets the field span its pane past the 40rem M3 bounds it to
     from `medium`. Every other attribute reaches the `<input>`: `type`, `min`, `step`,
     `readonly`, `wire:model` and the rest. Errors are read from the bag under the `wire:model` name.

     The placeholder is a single space when none is given, because the label can only tell an
     empty field from a filled one through `:placeholder-shown`. With a label, a real placeholder
     shows only while the field has focus — until then the label stands where it would be.

     The field's root carries `data-md-input`; everything it draws is the field's chrome
     (resources/css/components/field.css), which resources/css/components/input.css imports. --}}
