Thanks guys. We use a very old version of HTML Kit right now that supports a lot of interesting plugin stuff, and we have made a lot of menu items that look like the following:
That is a drop down menu we get to by clicking the little arrow on the side of the menu button. So not only can you click the menu button to get a default behavior, but you can click the little drop down next to it to get a big multicolumn menu. It's really handy.
Problem is, we are wanting to move to using newer software, but have not found anything that gives us many of the things we rely on as far as plugin support.
Thank you for the information though. I appreciate it.
