Im fairly new to building a html/css website, but Ive built a template with a Nav with hover effects. It works fine when viewing on desktop or tablet. On mobile I have a hamburger menu icon which when clicked on displays a menu as a vertical list. The top level Menu names display ok, but when hovering over them to show the sub menu items, I cant get the code right to so the space between each Top level menu name is expanded to then fit the sub menu vertical list between. It seems to overlay over the top level menus (see the screenshot Ive attached).Mobile view screencap
I’ve been unable to work this out so any help pointers would be gratefully received.
Ive included the HTML and CSS below so apologies for the length.

When i hover over a top level menu, I would like the space between each of these to expand and be filled by the sub menu. (hope this makes sense).
