How to change dropdown / ellipses functionality in Edition theme?

Hi! I was able to add dropdown functionality thanks to folks on this forum.

However, the ellipses (…) is being added too soon (see below).

I would expect it to be used only when space is an issue, which is not currently the case.

Also, the ellipses was only added after I included “Farmer’s Market” as a subitem in the dropdown list (it’s longer and more words than the other subitems).

So it appears when ellipses are added is in part determined by the length of dropdown subitems.

How can I change this functionality to show top level menu items and only start using an ellipses when space is an issue at the top level section only?

Thanks for any help folks can provide?
