Customizer Multiselect is a control that allows you to select multiple values from a list of options.

### Installation
Copy the folder in the root of your theme and add the following function in `functions.php` or `customizer.php`.
    
    function load_customize_classes( $wp_customize ) {  
        require get_template_directory() . '/customizer-select-multiple/class/class-customizer-select-multiple.php';
        $wp_customize->register_control_type( 'Customizer_Select_Multiple' );
    }
    add_action( 'customize_register', 'load_customize_classes', 0 );
    
### How to use?  
Add a control in your `customizer.php` file like this:

    if ( class_exists( 'Customizer_Select_Multiple' ) ) {
        $wp_customize->add_setting(
            'control_name', array(
                'sanitize_callback' => 'sanitize_array',
            )
        );
        $wp_customize->add_control(
            new Customizer_Select_Multiple(
                $wp_customize, 'control_name', array(
                    'section' => 'your_section',
                    'label' => esc_html__( 'Team members to appear on blog page', 'ace' ),
                    'description'   => __( 'Select multiple options.', 'ace' ),
                    'choices' => array(
                        'member1' => __('Larry','ace'),
                        'member2' => __('Michael','ace'),
                        'member3' => __('Jordan','ace'),
                    ),
                    'priority' => 1,
                )
            )
        );
    }
For sanitize I use this function:

    /**
     * Function to sanitize controls that returns arrays
     *
     * @since 1.1.40
     * @param mixed $input Control output.
     */
    function sanitize_array( $input ) {
        $output = $input;
        if ( ! is_array( $input ) ) {
            $output = explode( ',', $input );
        }
        if ( ! empty( $output ) ) {
            return array_map( 'sanitize_text_field', $output );
        }
        return array();
    }
    
To get the input from your control just call it in the normal way:

    $customizer_multiselect = get_theme_mod('control_name' );
    echo var_dump( $customizer_multiselect );
