 *    		'label' => __( 'Border Style', 'plugin-domain' ),
 *    		'type' => Controls_Manager::SELECT,
 *    		'default' => 'solid',
 *    		'options' => [
 *    			'solid'  => __( 'Solid', 'plugin-domain' ),
 *    			'dashed' => __( 'Dashed', 'plugin-domain' ),
 *    			'dotted' => __( 'Dotted', 'plugin-domain' ),
 *    			'double' => __( 'Double', 'plugin-domain' ),
 *    			'none'   => __( 'None', 'plugin-domain' ),
 *    		],
 *    	]
 *    );
 *

 *
 *    echo '<div style="border-style: ' . $this->get_settings( 'border_style' ) . '"> ... </div>';
 *
 * JS usage (inside `Widget_Base::_content_template()` method):
 *
 *    <div style="border-style: {{ settings.border_style }}"> ... </div>
