How to create a link that goes to the contents of the accordion tab?

Question

JavaScript

Welcome all! There is a menu on the first page, and an accordion on the second related within the same site. How to make it so that when a menu item is clicked, a page opens with the corresponding expanded tab? This is how the anchor transmits and goes to the page, but does not open the corresponding tab ..
