Description

Hi,

I have more than one selection filter,
"Publisher" filter and "Campaign Type" filter.
if I have selected the "Publisher" filter, then the results for the select "Campaign Type" filter should be chained.
But, it doesn't work well. Have to refresh the page to get correct results on "Campaign Type" filter.
How to refresh property "Campaign Type" filter when triggered from selected "Publisher" filter ?

class DatatableOfObjectives extends LivewireDatatable
{
    public $exportable = true;
    public $export_name = '';

    protected $listeners = [
        'refreshDataTable' => 'refreshTable'
    ];

    public function __construct()
    {
        $this->export_name = 'Data Objectives ' . date('YmdHis');
    }

    public function builder()
    {
        return MsObjectives::query();
    }

    public function columns()
    {
        return [
            NumberColumn::name('id')
                ->label('ID')
                ->defaultSort('asc')
                ->sortBy('id')
                ->hide(),

            Column::name('ms_publisher.name')
                ->filterOn('ms_publishers.name')
                ->filterable( $this->publishers->pluck('name') )
                ->label('Publisher'),

            Column::name('ms_campaign_type.name')
                ->filterOn('ms_campaign_types.name')
                ->filterable( $this->campaign_types->pluck('name') )
                ->label('Campaign Type'),

            Column::callback(['id', 'name'], function ($id, $name) {

                    return view('livewire.panels.masters.objectives.manage', [

                        'name' => $name,
                    ]);

                ->unsortable()

                        $filter_publisher = $session['select'][1];
                    
                        return $query->whereIn('ms_publishers.name', $filter_publisher);
                    })
                    ->get();
    }

Research direction

Start with DatatableOfObjectives::getCampaignTypesProperty and refreshTable, then inspect how the datatable stores selected filters and triggers Livewire updates. Reproduce the Publisher and Campaign Type selection sequence. Done means Campaign Type options update after Publisher changes without requiring a page refresh.
