Dang I can't edit above or I will lose that pretty edge!

@Dimster or @mnrvovrfc try out the above code, I have the code "rolling down" (each panel drawn after last instead of all at once) the menu items after a menu title button is clicked. I think this is the animation desired?
b = b + ...

The code is OK on my side. The animation is done like on mine but it's less obvious from just looking at the code.

The really long descriptions as part of menu entry could be hard. It might be better to have "Help" drawers instead that open a message box or other dialog that describes something in detail. Personally I don't like long menu entries. Although I had to deal with that regularly on REAPER, because it could be important in a music-creation application with many choices and which is deeply configurable.

Thanks b+ , that animation is working great for me. I've been playing with the Limit to speed up and slow down the drop. This is such an improvement over the old days when you had to erase and redraw the dropping box to create that animation effect.

I know what you mean Minerva on long descriptions as, in the past, I only used the Main Menus to offer options and the Dropping Box to display more menu items. I had no long descriptions, but after trying to adapt Tempodi's child windows, I came to realize that the Main Menu could display a variety of topics (as opposed to options) and the multiple drop boxes  display the various info items on the selected topic. This does call for a long descriptive box.

Anyway, this version of the drop box amazing. Thanks again

It still needs to be tested in real apps to see if really useful.
