I am having a wee bit of a problem with the AnyLink Vertical Menu.

My main menu has 25 menu items. That presents no difficulties.

Some of my submenus have 60 or more submenu items. That creates problems.

The problem is that the dynamic popup menu doesn't seem to be scrollable past the screen size. On my screen, I see a few dozen menu items and the rest of the menu items are unreachable. Items that are below the bottom edge of the screen cannot be scrolled to.

Is this a limitation of the script, or of the technology? i.e. is this fixable?
