Template:Dropimage/doc

DROPIMAGE. Place text for a heading in parameter one position. Place definitions for images, galleries, text, or an HTML table in parameter two position. The content hides initially in the collapsed state, and drops when the link button is clicked. The link toggles to collapse and expand the drop control.

The initial width of the control is not necessarily the dropped width, since the control expands to display the contents. The width option sets the initial width. the drop contents can contain links. The template can be nested. http://en.wikibooks.org/wiki/Template:Dropimage
