We have top navigation headers in our website, configured in the configuration file under the "navigation" tab under the "layout" tab. When the text header is hovered over it reveals the linked sub categories in a drop down. This was created by NS for us. Is there a way to make the drop down revealed when the top text header is clicked instead over a hover over?

Yes there is a way to do that, I will need to look at each of those Tab, I think it's under Advanced or shopping, I haven't done SCA stuff in 3 years so can't remember on top of my head

I have these 2 screenshots. Is that enough? Thank you

hmm not really, there is a help option maybe that will tell you. I am 95% confident it's on the screenshot you shared.

You could also try in #C29HR0BFG, its very active

here are the advanced and shopping catalog screenshots. Not seeing anything but thank you

hmm I think #C29HR0BFG might be better place, not ringing bell
