Sure, try the below modified .js file, which lets you define a category text that is shown on the top of each column within a drop down menu, such as in the screen shot below:

To define category text for a drop down menu, inside menucontents.js, add the line in red below to the corresponding menu contents:
Code:
var anylinkmenu3={divclass:'anylinkmenucols', inlinestyle:'', linktarget:'secwin'} //Third menu variable. Same precaution.
anylinkmenu3.cols={divclass:'column', inlinestyle:''} //menu.cols if defined creates columns of menu links segmented by keyword "efc"
anylinkmenu3.items=[

anylinkmenu3.categories=["Webmaster", "Search", "News"]
Here I'm extending anylinkmenu3 with a new categories property. Since this menu has 3 columns, I define 3 category text.
