getFilter inside of filters method

[mitchellholzmann]

Hi,

I'm currently trying to make a nested style datatable. Basically I want to be able to update a filter select based on the parent that was chosen. I was hoping I could grab a filter with getFilter, but it returns server errors (502) when I attempt this.

public function filters(): array
{
    // Get the set parent to grab the children of the current selection.
    // Return the root categories if no parent is selected.
    $parent = null;
    if($this->getFilter('parent')) {
        $parent = $this->getFilter('parent');
    }

    return [
        'parent' => Filter::make('Parent Category')
            ->select(Taxonomy::where(['type' => 'category', 'parent_id' => $parent])->pluck('name', 'id')->toArray())
    ];
}

Maybe fire an event on the child and listen on the parent?
