Php layers menu is a hierarchical menu system to prepare "on the fly" dhtml menus relying on the php scripting engine for the processing of data items.

it supports a wide range of browsers: mozilla, konqueror, netscape, safari, opera, internet explorer; rather old browser versions are supported, too; accessibility is provided for text-only browsers.

it achieves a compact layout and a compact output code also for menus with a large number of entries.

it provides horizontal and vertical layers-based menus whose behavior is analogous to menus of commonly used gui-based applications. it also provides javascript-based tree menus, whose look is analogous to the most widely used file managers and bookmark handling tools.
