/**
 * Select2 control.
 *
 * A base control for creating select2 control. Displays a select box control
 * based on select2 jQuery plugin @see https://select2.github.io/ .
 * Accepts an array in which the `key` is the value and the `value` is the option
 * name. Set `multiple` to `true` to allow multiple value selection.
 *
 * Creating new control in the editor (inside `Widget_Base::register_controls()`
 * method):
 *
 *    $this->add_control(
 *    	'show_elements',
 *    	[
 *    		'label' => __( 'Show Elements', 'plugin-domain' ),
 *    		'type' => Controls_Manager::SELECT2,
 *    		'default' => 'solid',
 *    		'options' => [
 *    			'title' => __( 'Title', 'plugin-domain' ),
 *    			'description' => __( 'Description', 'plugin-domain' ),
 *    			'button' => __( 'Button', 'plugin-domain' ),
 *    		],
 *    		'multiple' => true,
 *    	]
 *    );
 *
 * PHP usage (inside `Widget_Base::render()` method):
 *
 *    $show_elements = $this->get_settings( 'show_elements' );
 *    foreach ( $show_elements as $element ) {
 *    	echo '<div>' . $element . '</div>';
 *    }
 *
 * JS usage (inside `Widget_Base::_content_template()` method):
 *
 *    <# _.each( settings.show_elements, function( element ) { #>
 *    	<div>{{{ element }}}</div>
 *    <# } #>
