Custom taxonomy for filter

The Filter element lists the Portfolio categories and tags. To let it list a custom taxonomy as well, use one of the two methods below.

A. Method with PHP code

The vpf_allow_taxonomy_for_filter filter decides whether a taxonomy may be used in the Filter. Return true for the one you want:

<?php

add_filter( 'vpf_allow_taxonomy_for_filter', 'my_filter_vpf_allow_taxonomy_for_filter', 10, 2 );

function my_filter_vpf_allow_taxonomy_for_filter( $allow, $taxonomy ) {
    if ( 'my_custom_taxonomy' === $taxonomy ) {
        $allow = true;
    }
    return $allow;
}

B. Method with settings

You can also add the custom taxonomy slug in the plugin settings, without writing any code:
