wordpress wp_nav_menu custom id

First, go to your WordPress dashboard and navigate to "Appearance" and then "Menus." Next, click on "Screen Options" at the top of the page and make sure "CSS Classes" is checked. Find the menu you want to customize or create a new one. Add a custom link to your menu and fill in the URL and link text. Then, in the "CSS Classes" field for that custom link, add your desired ID name. Lastly, save the menu and use the custom ID in your theme's CSS or JavaScript files as needed.
