I have looked all over and cannot find any information on this.
What I am after is a navigation, by which there are a series of buttons(main buttons that dont actually go anywhere or link to a page, instead what they do will be to drop a series of links below.
But when you click on a second main button, the previosu reverts back up and the new drop appears.
The reason, otherwise I would have all my buttons in one place below each other and this would take up much room, by which this should be reduced with this method for soley the interested area of options.
Its similar to how that really cool XML menu works, but no where near as difficult, its the effect I require not the xml workings, just how it operates.
