Displays a panel that can be collapsed or expanded by users. The panel contains a web part zone, so any type of content may be added.
To insert content into the panel, edit the document where it is placed on the
Design tab of
CMS Desk and make sure that the
Display web part content option is enabled (using the checkbox in the header of the tab menu). This way, you can expand the panel and add any web parts that you need into the zone.
