Please help me, i don't understand the FAQ?

In an ideal world you should contact the theme author and ask them to patch the theme for compatibility.

The numbering in the FAQ is messed up but it says to find the start_el() method that looks like:

function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {

and inside that method you need to paste my hook:

<?php
// Add this directly after the description paragraph in the start_el() method
do_action( 'wp_nav_menu_item_custom_fields', $item_id, $item, $depth, $args );
// end added section
?>

as mentioned in the FAQ i think it is best to paste this just after the “definition” section.

I figured out what i was doing wrong, the line 65 was the line i needed to replace with

add_filter( ‘wp_edit_nav_menu_walker’, ‘sample_edit_nav_menu_walker’);
function sample_edit_nav_menu_walker( $walker ) {
return ‘Walker_Nav_Menu_Edit_Roles’; // this is the class name
}

the thing is, i wasn’t changing the name of the sample to my themes name, the only thing im not sure of if this will mess up anything in my theme since i’m replacing the nav menu walker with something new, cause I’ve tried adding both at once and it doesn’t work. But i hope it won’t, thanks a lot, for the support, great plugin.

No, you do not need to replace the sample_edit_nav_menu_walker() function (or your theme’s equivalent). you need to patch the Walker itself. Otherwise, the theme and NMR will not play together. Again, I strongly encourage you to contact the theme author to make this change permanent.

If Walker_Nav_Menu_Edit_Roles is the name of the Walker then there will be a class somewhere in the theme with that name and you need to patch that with the do_action() code I posted above.
