Select a node in the navigation tree, open the context menu, and choose the "Edit" menu entry to open the Edit Metadata dialog.
The Edit Metadata dialog for nodes does not offer a preview. It only consists of metadata tabs.
By default, the node metadata dialog only has the "General" metadata tab, which allows you to enter the node's name for each configured user interface language. Here, you also set the validation level and the icon for the node. However, your technical server administrator can configure other metadata tabs.
Confirm your changes with "Finish".
You can only edit metadata for one node at a time.
