Choose from a selection of over 200 graphics buttons or use one of your own. Simple text based buttons are also supported. Up to 20 separate drawers per page can be created using Joomla module copy feature.
This module is also compatible with the the Blackdale media addon (free) which extends the integral range of backgrounds and surrounds.
No need to register.
What's more, the developer of this free app was kind enough to help me track down and fix a problem caused by another developers extension.
Outstanding extension, outstanding service.
