Html::widgets::selectlayers implements an html widget with multiple layers. only one layer is visible at any given time, controlled by a box. for an example see http://www.420.am/selectlayers/

this html generated by this module uses javascript, but nevertheless attempts to be as cross-browser as possible. the 0.05 release drops navigator 4 compatibility and has been tested under mozilla firefox 1.0.6, msie 6.0, konqueror 3.3.2, and opera 8.0.2.
