Allowing multiple values per task

Most label trees act like a field: one value per tree. Some trees are better as plain tags, where a task can carry several values at once:

Turning it on

Open the tree's top label on the Labels page and toggle Allow multiple per task in its Edit dialog. The toggle lives on the top label and applies to the whole tree. Trees that allow multiple values are marked with a layers icon.

You'll see a confirmation when turning it on — once the tree allows multiple values, it stops acting like a single-choice field, and tasks can accumulate several labels from it.

Turning it off

A tree can only go back to single-value when no task carries more than one label from it. If some tasks still hold several values, Nydli refuses the switch and tells you — remove the extra labels from those tasks first, then turn the toggle off.
