My apologizes if this has been answered before.

Is there a way to populate a select drop down, in my Post Field Group, that uses categories already setup in my wordpress page categories? I have a list of over 300 that need to be assigned to the drop down.

Thanks!

Hi! There's not currently a way to do this from the wp-admin area, but there is a PHP solution noted in another post:
https://toolset.com/forums/topic/i-wish-i-could-load-a-custom-select-with-options-from-a-custom-taxonomy/

add_filter( 'wpt_field_options', 'fill_select', 10, 3);
function fill_select( $options, $title, $type ) {
    if ($title == 'my-custom-select')  {
        $options = array();
        $args = array('hide_empty' => 'false');
        $terms = get_terms( array('my-taxonomy'), $args );
         
        foreach ($terms as $term) {
            $options[] = array(
                '#value' => $term->term_id,
                '#title' => $term->name
            );
        }
    }
}

Add this code to your functions.php file. Obviously you'll have to replace 'my-custom-select' and 'my-taxonomy' with the correct slugs for your site. Let me know if you need assistance, and I'll take a deeper look.
