WebListBox inside a WebListBox Cell?

Is there a way to get a WebListBox inside a cell of a WebListbox?

No. What are you trying to accomplish?

Something like a treeview but a tree of listboxes.
The hardest part is trying to get select all and row expand checkboxes into columns of WebListBox.
The rest for me is cell formatting with Styles.

You’d be better off using WebContainers or the WebSDK.

Just looking at the WebContainer examples as we speak.

Seems to be working fine for me…

Had to restart my firefox, but then it worked.
