On the Edit Screen in the WP Admin there is a meta box for WP’s built-in Category taxonomy. This meta box is built using post_categories_meta_box() (/wp-admin/includes/meta-boxes.php).
I am relatively new to wordpress development, I am trying to extend ‘Walker_Category_Checklist’ class found in /wp-admin/includes/class-walker-category-checklist.php to customize it for wp_terms_checklist() or wp_category_checklist() but when I try to require_once a link to my extended class in the child-theme function.php I get this error and site not loading!
I’d like to make a custom walker that works with wp_list_categories to generate a menu of nested uls using my category, sub-category, and sub-sub-category(?) structure. Any category that has sub-categories can’t be a link so it can be clicked in order to reveal the sub-categories (or sub-sub-categories).
I am trying to add the featured image of posts to my mega menu. I want to display the featured image inside a div tag. How would i add the featured image inside of a sprintf function?
Normal WordPress Menu looks like:
I’m wondering if it is possible to add different classes to second/third/fourth/etc-level items that have children in Appearance > Menus tree?
Currently I have a structure where the top level categories are acting like landing pages, so they should have no posts directly assigned to them. What I would like to do is disable the top level terms and only allow the user to check sub-terms (children). I’ve found a walker which transforms checkboxes to radio buttons here but I don’t quite understand it enough to only change the top level parent, it keeps cascading. Was hoping somebody could break down what is going on in this walker with the main question being “How do I disable top level terms in the admin panel term metabox”
Can someone explain to me how the Walker Class works? Do the methods inside the class always need to overload the parent method?
I know this question has been asked in different forms. But as far as I can tell from searching Google and SE/WP it’s never been satisfactorily answered.
I’m creating a custom walker for my nav menu. The goal is to split the menu in to columns like so:
