It seems that some of your templates support this. Others don't. All my customers want it because it's common on WordPress sites. They really like it. I've used JA University quite a bit, and that supports it. I probably have to add some PHP code somewhere to make it work on your other templates? Which ones have it built-in? To be clear, the good old "fixed" position works. That's not what we need. We want to use "sticky," so that header scrolls up and off the screen but the menu sticks to the top as user scrolls down. You can see it on my company site, javelincommunications.com. Maybe there is an answer in the forum but I haven't been here in awhile and it wasn't apparent how to search. I did survey what comes up in Google, but none of it was totally on point. Thanks to anybody for any help.
