This jQuery plugin, developed in the iHwy Labs, allows you to easily convert a long, hard to navigate list into a compact, easily skimmable ‘first-letter’ based menuing system, allowing quick and ‘out-of the-way’ access to hundreds of items. Users hover their mouse over a letter and a columnized list of all of the list items that start with that letter appear in a submenu. Mousing off of the letter or menu closes the submenu. Mousing between letters is very fast and the columns in the submenu are nicely balanced.
