Add SearchPane

SearchPanes (example) allow the user to quickly filter the datatable after predefined filters.

{note} To use datatables you need to make sure that the npm packages datatables.net-select-bs4 and datatables.net-searchpanes-bs4 are installed and added to your app.js/app.css files.

Adding SearchPanes to the frontend

To be able to see SearchPanes you need to either add them fixed in the dom (displayed at all time) or add a button which opens them as popup.

Adding SearchPanes fixed in the dom

SearchPanes can be added to a table via the dom string, in it, they are marked with a P if you for example are using Bfrtip as dom you can use PBfrtip to display the SearchPanes at the top of the datatable, or BfrtipP to display them at the very bottom.

Setting the dom String with the \Yajra\DataTables\Html\Builder:

public function html() : \Yajra\DataTables\Html\Builder
{
    // Setting the dom string directly
    return $this->builder()
        ->searchPanes(SearchPane::make())
        ->dom('PBfrtip');
 
    // Alternatively set the dom with parameters
    return $this->builder()
        ->searchPanes(SearchPane::make())
        ->parameters([
            'dom' => 'PBfrtip'
        ]);
}

Adding SearchPanes with a button

To add a button which opens the SearchPanes you need to make one extending searchPanes:

public function html() : \Yajra\DataTables\Html\Builder
{
    // Adding via class
    return $this->builder()
        ->searchPanes(SearchPane::make())
        ->buttons([
            \Yajra\DataTables\Html\Button::make('searchPanes')
            // other buttons...
        ]);
 
    // Alternatively set the buttons with options
    return $this->builder()
        ->searchPanes(SearchPane::make())
        ->parameters([
            'buttons' => ['searchPanes', /*other buttons...*/]
        ]);
}

Adding SearchPanes to the backend

The SearchPanes can be filled in the datatables declaration via the searchPane() method. The method takes the column for which the SearchPane is, as well as the options of the SearchPane. It also allows you to set custom processing for the options.

public function dataTable($query) : Yajra\DataTables\DataTableAbstract
{
    return datatables()
        ->eloquent($query)
        // Adding the SearchPane
        ->searchPane(
            /*
             * This is the column for which this SearchPane definition is for
             */
            'user_id',
 
            /*
             * Here we define the options for our SearchPane. This should be either a collection or an array with the
             * form:
             * [
             *     [
             *          'value' => 1,
             *          'label' => 'display value',
             *          'total' => 5, // optional
             *          'count' => 3 // optional
             *     ],
             *     [
             *          'value' => 2,
             *          'label' => 'display value 2',
             *          'total' => 6, // optional
             *          'count' => 5 // optional
             *     ],
             * ]
             */
            fn() => User::query()->select('id as value', 'name as label')->get(),
 
            /*
             * This is the filter that gets executed when the user selects one or more values on the SearchPane. The
             * values are always given in an array even if just one is selected
             */
            function (\Illuminate\Database\Eloquent\Builder $query, array $values) {
                return $query
                    ->whereIn(
                        'id',
                        $values);
            }
        );
}
