Adding different left sidebar on category pages

Hello,

Try to add the below code to the child theme’s functions.php file to change the sidebar. You can create a new sidebar using the Ocean Sidebar plugin. Edit the sidebar id in the code with the new sidebar id that you will create.

function prefix_cpt_sidebar( $sidebar = 'sidebar' ) {

    if ( is_singular( 'mphb_room_type' ) ) {
        $sidebar = 'sidebar-2';
    }

    return $sidebar;

}
add_filter( 'ocean_get_sidebar', 'prefix_cpt_sidebar' );
