Hierarchy Filterpane
There is a lot of interest from a client to be able to make selections in fields that are associated with a hierarchy. They want to click and expand a dimension and see subordinate dimensions easily at the same time without drill down that only lets you see one level at a time.
The client wants something very much like this legacy extension: https://github.com/Steckmaestro/QlikHierarchyFilterpane.
However, QlikHierarchyFilterpane is an unsafe choice because it is no longer updated.
The client is not a Vizlib user today but could become one if this need is met.
Please see the example from QlikHierarchyFilterpane inside the red box in the attached image.
