    'type'    => 'checkbox_list',
    // Options of checkboxes, in format 'value' => 'Label'

    // Display "Select All / None" button?
    'select_all_none' => true,


This field saves multiple values in the database. Each value is stored in a single row in the database with the same meta key (similar to what add_post_meta does with last parameter false).

If the field is cloneable, then the value is stored as a serialized array in a single row in the database.

Template usage

If field is not cloneable:

$values = rwmb_meta( $field_id );
foreach ( $values as $value ) {
    echo $value;

If field is cloneable:

$values = rwmb_meta( $field_id );
foreach ( $values as $clone ) {
    foreach ( $clone as $value ) {
        echo $value;

The function rwmb_meta() only returns the value of the field, e.g. the key in the options array. To display the field label, use this code:

rwmb_the_value( $field_id );

which outputs:
