Hello,

Is there a code for me to use to be able to have my menu links underlined when hovering over them and also being underlined when on that page?

Thank you

You would use CSS for that.

The simplified explanation is use

a:hover

and

text-decoration: underline

along with other selectors to underline the links on hover. To have them underlined when on that page you would use

.current-menu-item

or

.current_page_item

along with other selectors and the text-decoration CSS to have it underlined when on the page.
