    I use the "taxonomy advanced"-field in a frontend form to select topics for blog entries. People could select multiple categories - so far everything works well - but I need a maximum amount for the selection. I couldn't find the possibility in the documentation for the "taxonomy advanced"-field. Is it possible to limit the number to three?

    Thanks for your support,
    Andi

    Hi Andreas,

    You can allow the user to select one category per input box. Then enable the cloneable setting and set the max_clone setting to 3. Here is the sample code:

    [
    'name'           => __( 'Taxonomy', 'your-text-domain' ),
    'id'             => $prefix . 'taxonomy_rbgrdv9a23p',
    'type'           => 'taxonomy_advanced',
    'taxonomy'       => ['category'],
    'field_type'     => 'select_advanced',
    'clone'          => true,
    'max_clone'      => 3,
],
