Flooble Hierarchical Select Menu is multi-platform compatible. Ever have an HTML form with a select Menu so big that you wish you could make it easier to use? Perhaps what you need is a hierarchical select. Most software you have on your computer has the functionality: if a menu becomes too long, developers usually break it up into sub-menus for easier management. These often have multiple levels of depth - this is why they are called "Hierarchical Menus". Unfortunately, HTML does not have this nifty option. Web designers are stuck with the same old <SELECT> Menu, which can only list options linearly. There is of course the little-known <OPTGROUP> tag, but browsers choose to list all the groups in one long linear list, so there are very little actual advantages to its use...
