Custom walker nav - Add sequential number as classI'm getting to grips with the walker at the moment, but i need some assistance in getting my desired effect. My walker function looks like: class ik_walker extends Walker_Nav_Menu{ //start of the sub menu wrap function start_lvl(&$output, $depth) { $output .= '<nav class="site-navigation" role="navigation"> <ul>'; } //end of the sub menu wrap function end_lvl(&$output, $depth) { $output .= ' </ul>
