In the current version the Structure Gadget in Confluence is supported, but some issue may occur. This will be fixed in the future versions.
You can embed Structure Gadget in a Confluence page and view or edit structure in Confluence.
Before you can use Structure Gadget on a Confluence page, your Confluence administrator must add Structure Gadget to Confluence Configuration. If you try to insert a macro and don't see Structure in the list, most likely the gadget is not configured.
The displayed Structure gadget is not suitable for printing. Support for printable Structure gadget is coming later. For now, please use Printable Page to print a structure separately.
