Empty value for PickTreeItem

[Isomorphic]

Sorry, we misnamed the property. It's actually dataSetType:

That would be great, but I don't see a "dataModelType" property in the online docs nor attached to a SelectItem when inspecting the client form item instance. I'm using the client only components V13.

You can just use a SelectItem and set the dataModelType to tree, then you get a drop-down that basically works like a TreeGrid, and you can use specialValues and other pickList features.

Bump...
Is there a way to clear a selection (default to root) such as either showing the root value in the dropdown (setting the item's valueTree showRoot=true doesn't work), or having "specialValues" as in a picklist? I can add a button to the form to "Clear Selection" (set the pickTreeItem value to whatever), but it would be better if it was in the dropdown selection itself, if possible.

If you use a valueField *and* displayField, the valueField can be null and the displayField can have something like "[Empty]" or whatever you want to show to the end user for an empty value.

Is it possible to have an empty value for a PickTreeItem after selecting a value?

If you look at the example at https://www.smartclient.com/smartcli...e/?id=pickTree, it starts with an "empty value", but after selecting it, it cannot be changed back to an empty value or can it?
