I'm creating my custom model form on a backend module. I need to allow the admins to select one category for my model, so I wanted to use the Magento standard category selector, like this example :
How can I do ?
FYI, I'm using form fieldset to add fields, like this example:
$fieldset->addField( 'field_name', 'text', [ 'name' => 'field_name', 'label' => __('Field Label'), 'title' => __('Field Title'), 'required' => false ] );
There are similar questions, but none of them has a valid answer for the moment.
