Currently this interface is not fully operational: impossible to select a subtree, impossible to switch back to no limitations,... The interface has been reworked using the UI guidelines https://projects.invisionapp.com/d/main#/console/12841697/268855342/preview

Elements to improve:

User / Group

• Validation on user and groups: the editor should not be able to submit if there is not user / groups selected
• Using UDW when selecting user / groups
• Add option to delete assigned user / groups

Limitations

• Add error messages when there is no specific section selected when user wants to limit by section
• Add error message when there is no specific subtree selected when user wants to limit by subtree
• UDW is not working on subtree selection
• Add the option No limitation, selected by default
• Add option to delete subtree
