This web part provides an accordion layout divided into multiple panes that can be expanded or collapsed. Each pane defines a separate web part zone, so any content may be added into the layout. Users can click on the pane headers to select which one should be displayed.
To insert content into the accordion layout, edit the document where it is placed on the Design tab of CMS Desk. Here you can select individual panes and add any web parts that you need into the corresponding zones.
