|
|
*
|
|
* 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>
|
|
* <# } #>
