If you do a Help Desk search for "drag panel", you'll get the following hits:

panel:dragable-mixin  provided from framework
panel:dragable<%>  provided from framework
panel:horizontal-dragable%  provided from framework
panel:horizontal-dragable-mixin  provided from framework
panel:horizontal-dragable<%>  provided from framework
panel:vertical-dragable%  provided from framework
panel:vertical-dragable-mixin  provided from framework
panel:vertical-dragable<%>  provided from framework

You probably want either panel:horizontal-dragable% or
panel:vertical-dragable% for your purposes; here are the URLs to their
online documentation:



Good luck!
