lists

An editable, sortable list of single values (one input per row) with add and delete buttons. Submitted as an array of strings.

Signature

Lte3::lists(string $name, array $items = [], array $attrs = [])

{!! Lte3::lists('countries', ['Ukraine', 'Poland', 'France'], [
    'label' => 'Countries:',
    'placeholder_value' => 'Title',
]) !!}

$items is a flat array of values, one row each. An empty array renders one empty row.

The component does not read the form model, old() or default: pass the items explicitly, e.g. old('countries', $settings->countries ?? []).

Attr	Type	Default	Description
`label`	string	`Str::studly($name)`	Label HTML. `''` hides it.
`help`	string	-	Help HTML under the list.
`placeholder_value`	string	`Value`	Placeholder of the inputs; rendered rows get the row number appended (`Title 1`, `Title 2`).
`input_type_value`	string	`text`	`type` of the inputs in rendered rows.
`class`	string	-	Extra classes of the wrapper `.form-group.f-lists` (this component has no `class_wrap`).
`hidden_wrap`	bool	`false`	Hides the whole field.

field_attrs keys and attrs are not printed.

countries[]=Ukraine
countries[]=Poland
countries[]=France

Rows added in the browser get explicit indexes (countries[3]), so the array keys may not be sequential. PHP keeps the order the rows appear in the form; use array_values() for a clean list.
Empty rows are submitted too.

$countries = array_values(array_filter($request->input('countries', []), 'filled'));

Validation errors are shown for the field name itself (countries), not for countries.0.

+ inserts an empty row after the current one, - removes the current row; the last remaining row cannot be removed. Both are delegated click handlers, so they work in content inserted later.
Rows added by + always use type="text" inputs.
Sorting: rows are in a tbody.sortable-y, made sortable by initSortableY(root) (jQuery UI), see JavaScript API.
