* Using the same menu twice on the same page results in a “duplicated IDs” error
in HTML validation, because the list elements of the typical wp_nav_menu() output
get an id=”menu-item-ID”.
* So if we use our Main-Navigation as a sitemap-like list in the footer, the HTML
fails validation.
* Because I found no way to filter your plugin output, I helped me “dirty” by adding
a page-wide filter.
* ```
function remove_menu_ids () {
add_filter( 'nav_menu_item_id', '__return_null' );
}
add_action( 'init', 'remove_menu_ids' );
```
* Would be nice, to have your plugin handle theese duplicated IDs.
