pmpromd-hide-empty-elements.php

<?php
/**
 * Hides empty elements on the directory and profile pages.
 *
 * Can be useful if you have a select type user field
 * and you don't want to display them if they are empty.
 * This requires the first select field option to be configured
 * with no value set, a colon, and a label set. e.g. ":label".
 *
 * For example:
 * :-- Select One --
 * dogs:Dogs
 * cats:Cats
 *
 * You can add this recipe to your site by creating a custom plugin
 * or using the Code Snippets plugin available for free in the WordPress repository.
 * Read this companion article for step-by-step directions on either method.
