State Emitters Use ? Some Example ?

Hi Francesco

Awesome to see you’re developing for the Widgets Bundle! And especially awesome to see you’re using state emitters. It’s a really powerful new feature we added in a recent update.

So the first step will be to attach a state emitter to your slider_type field. This will emit the state to the rest of the form.

'slider_type' => array(
	'type' => 'radio',
	'label' => __( 'Select type of Slider', 'widget-form-fields-text-domain' ),
	'options' => array(
		'1' => 'Slider 1',
		'2' => 'Slider 2'
	),
	'default' => '1',
	'state_emitter' => array(
		'callback' => 'select',
		'args' => array( 'slider_type' )
	),
),

The next step is to add a state handler to your slider_2 field. This will handle the slider_type state by showing the field if this state is set to 1 and showing it if it’s set to 2.

'slider_2' => array(
	'type' => 'select',
	'label' => __( 'Select  Slider 2', 'widget-form-fields-text-domain' ),
	'options' => $array_slides2,
	'state_handler' => array(
		'slider_type[1]' => array('hide'),
		'slider_type[2]' => array('show'),
	)
),

Hope that points you in the right direction. Here’s a complete guide on using state emitters – https://siteorigin.com/docs/widgets-bundle/form-building/state-emitters/
