Hello, I’m making my own nested element, I have refer to the Bricks’ accordtion-nested.php and slider-nested.php. There is one control I don’t understand its purpose and usecase which is 'titleProperty' => 'label' from:
public function set_controls() {
$this->controls['sections'] = [
'type' => 'repeater',
'titleProperty' => 'label',
'items' => 'children'
];
}
There is no definition as what it does and why we need it, can you please explain on this?
