Show and edit join table attributes

Configuration show and edit join table attributes

When this option is enabled, the link manager dialog will show the linked features in a tree structure instead of a simple list. The tree elements can be expanded to show the attribute form of the join feature. The attribute form can be configured as usual in the layer properties of the join layer.

Join feature editing

Note: If a feature is not respecting the constraints, it will not be linked/modified when the dialog is accepted. Other features with valid attributes will still be linked.
