RedotRepeater

The engine behind the <x-repeater> component: a repeatable group of form fields the user can add, remove, reorder, and clear. On submit it serializes the rows into the field as an array (name[0][field], name[1][field], …). Use the component — this plugin is wired up for you by the repeater init.

Usage

The component's default slot is the template that gets cloned per row. Mark action buttons with an action attribute and a drag handle with sortable-handle:

<x-repeater id="contacts" name="contacts" :title="__('Contacts')" :value="old('contacts', $contacts)">
    <div class="card mb-2">
        <div class="card-body">
            <x-input name="name" :title="__('Name')" />
            <x-input name="email" :title="__('Email')" />

            <div class="btn-list mt-2">
                <button type="button" class="btn btn-icon" action="insert"><i class="fas fa-plus"></i></button>
                <button type="button" class="btn btn-icon text-danger" action="remove"><i class="fas fa-trash"></i></button>
                <span sortable-handle class="btn btn-icon cursor-move"><i class="fas fa-grip-vertical"></i></span>
            </div>
        </div>
    </div>
</x-repeater>

Server-side you receive contacts as an array of objects.

Action attributes

Put these on buttons inside the template (or, for the static ones, anywhere in the repeater):

• action="insert" — add a row. Inside an item it inserts after that item; elsewhere it appends to the end.
• action="remove" — remove the containing row.
• action="clear" — remove every row.
• sortable-handle — marks the drag handle for reordering.

Options

Set these as repeater- attributes on the component tag:

• repeater-sortable — drag-to-reorder, on by default. Set false to disable.
• repeater-scrollable — scroll a newly added row into view (default on).
• repeater-confirmable — ask for confirmation before remove/clear (default on). Set false to skip.
• repeater-initial-items — number of empty rows to start with.

<x-repeater id="links" name="links" repeater-sortable="false" repeater-confirmable="false" repeater-initial-items="1">
    <x-input name="url" :title="__('URL')" />
    <button type="button" action="remove" class="btn btn-icon"><i class="fas fa-trash"></i></button>
</x-repeater>

Reacting to changes

The plugin fires jQuery events on the field as rows change — repeater:inserted, repeater:removed, repeater:cleared (each payload includes { repeater, item } where relevant):

$('#contacts').on('repeater:inserted', (e, { item }) => { /* ... */ });

Reach the instance later with $('#contacts').data('repeater').

Gotchas

• Field names inside a row are rewritten to name[index][field]; values only land in the field on form submit.
• Conditional-visibility (visible-when) inside a row is rewritten per row, so each row's conditions track its own fields — see Redot Visibility.
