Larastrap provides the ability to define your own custom element, just extending the existing ones and providing some configuration. Those can be paired with Javascript libraries and custom PHP functions to fine-tune the intended behaviour, and reuse across your code.
When you have some Laravel Model related (perhaps through a Polymorphic Relation) to many different other Model types, and you have to embed them in many different edit forms, you can define once a Composite widget to be used in multiple templates.
On submit, all the child inputs will be serialized within the same "dot notation" group.

You can define Bootstrap Alerts just as a Custom Element extending the Typography node. So you have far more flexibility than just the color, and define multiple types with specific CSS classes and specific behaviors.
The same applies to Bootstrap Badges.

A simple x-larastrap::text input can be decorated with a Bootstrap icon and marked with the .date CSS class, used to attach Bootstrap Datepicker (or whatever datepicker JS library you prefer) initialization.
Using reviewCallback it is possible to format the value before display.

'extends' => 'text',
'params' => [
'classes' => ['date'],
'placeholder' => 'Never',
'textappend' => '<i class="bi-calendar"></i>',

$params['value'] = ucwords(strftime('%A %d %B %Y', $params['value']));

[
'customs' => [
'hlink' => [
'extends' => 'link',
'params' => [
'reviewCallback' => function($button, $params) {
if (isset($params['attributes']['hreflang']) == false) {
$params['attributes']['hreflang'] = App::getLocale();
}
return $params;
},
]
],
]
]
<x-larastrap::hlink label="Just a Link" :href="route('homepage')" />
<a id="link-c692013b" class="btn btn-primary" href="https://larastrap.madbob.org" hreflang="en">Just a Link</a>
All headers internal to the Larastrap documentation are defined with a Custom Element translating the label into a link, for convenient and visibile internal linking.
The version actually used in this website also pushes each label/link pair to a singleton array, then used for automatic generation of the menu displayed on the top right for internal navigation.
[
'customs' => [
'linkedtitle' => [
'extends' => 'link',
'params' => [
'override_classes' => ['title-link'],
'reviewCallback' => function($node, $params) {
$identifier = Str::slug($params['label']);
$params['id'] = $identifier;
$params['label'] = sprintf('<h3>%s</h3>', $params['label']);
$params['href'] = sprintf('#%s', $identifier);
return $params;

<x-larastrap::linkedtitle label="Example 2" />

<h3>

</h3></a> <a id="example-2" class="title-link" href="#example-2">

'customs' => [

'extends' => 'button',
'params' => [

</div>With a reviewCallback applied to x-larastrap::tabpane it is possible to dynamically build its HTML label and keep the template clean and readable. In this example, text in the labels is hidden when displaying on mobile - so to have compact and pretty tabs even on small screens.

'mobiletab' => [
'extends' => 'tabpane',
'params' => [
'reviewCallback' => function($component, $params) {
if (isset($params['attributes']['icon'])) {
$params['label'] = sprintf('<span class="d-none d-md-inline-block me-2">%s</span><i class="%s"></i>',
$params['label'],
$params['attributes']['icon']

</div>One of the most basic usage of Custom Elements is to define input types with a specific role, usually identified by an icon or a suffix. An input for a monetary amount is probably the most classic example.
[

'params' => [
'textappend' => '€',
'attributes' => [
'step' => 0.01,

],

</div>What about injecting your Laravel Dusk selectors only when actually running Dusk tests? This can be in particular useful with x-larastrap::checks and x-larastrap::radios, and be able to select with precision your options and test your own combinations.

'reviewCallback' => function($component, $params) {
/*

$options = $params['options'];
$new_options = [];
foreach($options as $value => $option) {
if (is_object($option)) {
if (!isset($option->attributes)) {
$option->attributes = [];
}
}
else {
$option = (object) [
'label' => $option,
'attributes' => [],
];
}
$option->attributes['dusk'] = sprintf('%s-%s', $params['name'], $value);
$new_options[$value] = $option;
}
$params['options'] = $new_options;
}
return $params;
}
],
],
