Tagging Select

The Tagging Select controller allows users to enter multiple values as tags into a text field with a menu of options.

Demonstration

 
Handy::control( 'tagging-select', [
    'id'          => 'tagging_select_id',
    'section'     => 'layout_section',
    'label'       => esc_html__( 'Tagging Select Control', 'textdomain' ),
    'description' => esc_html__( 'Description Here', 'textdomain' ),
    'priority'    => 1,
    'choices'     => [
        'apple' => esc_html__( 'Apple', 'textdomain' ),
        'grape' => esc_html__( 'Grape', 'textdomain' ),
        'melon' => esc_html__( 'Melon', 'textdomain' ),
        'peach' => esc_html__( 'Peach', 'textdomain' ),
        'lemon' => esc_html__( 'Lemon', 'textdomain' )
    ]
]);

TIP

Here's an example using the default parameter. Note the default values must exist in defined choices.

 
Handy::control( 'tagging-select', [
    'id'          => 'tagging_select_id',
    'section'     => 'layout_section',
    'default'     => [ 'apple', 'grape', 'melon' ],
    'label'       => esc_html__( 'Tagging Select Control', 'textdomain' ),
    'description' => esc_html__( 'Description Here', 'textdomain' ),
    'priority'    => 1,
    'choices'     => [
        'apple' => esc_html__( 'Apple', 'textdomain' ),
        'grape' => esc_html__( 'Grape', 'textdomain' ),
        'melon' => esc_html__( 'Melon', 'textdomain' ),
        'peach' => esc_html__( 'Peach', 'textdomain' ),
        'lemon' => esc_html__( 'Lemon', 'textdomain' )
    ]
]);

TIP

Here's an example using the maximum parameter. Note the maximum value accepts only an integer data type.

 
Handy::control( 'tagging-select', [
    'id'          => 'tagging_select_id',
    'section'     => 'layout_section',
    'default'     => [ 'apple', 'grape', 'melon' ],
    'label'       => esc_html__( 'Tagging Select Control', 'textdomain' ),
    'description' => esc_html__( 'Description Here', 'textdomain' ),
    'priority'    => 1,
    'maximum'     => 5,
    'choices'     => [
        'apple' => esc_html__( 'Apple', 'textdomain' ),
        'grape' => esc_html__( 'Grape', 'textdomain' ),
        'melon' => esc_html__( 'Melon', 'textdomain' ),
        'peach' => esc_html__( 'Peach', 'textdomain' ),
        'lemon' => esc_html__( 'Lemon', 'textdomain' )
    ]
]);
