I want to remove certain input fields on the admin screen for nav-menus for specific menu positions. I’ve used filters to filter front-end output but not for admin output. Is there a filter available for this purpose?
For example, I want to remove the option to add a title
attribute to menu items, only if the menu is used in ‘position-x’.
Filters such as nav_menu_link_attributes
and wp_nav_menu_args
all seem to be to filter the front end output.
These fields are created in Walker_Nav_Menu_Edit::start_el()
. To change or to remove them, create a custom walker (example for another walker) that extends Walker_Nav_Menu_Edit
and uses other or less fields.
Then filter wp_edit_nav_menu_walker
and return the class name of your walker.
Pseudo-code:
class Walker_Nav_Menu_Edit_Simple extends Walker_Nav_Menu_Edit {
public function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 )
{ /* Magic here. */}
}
add_filter( 'wp_edit_nav_menu_walker', function() {
return 'Walker_Nav_Menu_Edit_Simple';
});
