Dear all,
For the need of a form, I need the user to select an unlimited number of tags from a tree with 5 levels. If I use sequential drop boxes for digging into each level and select a final keyword, the interface might be too complicated.
I was thinking about a left component with a tree representing the whole hierarchy and then a list of pickup keywords at the right. Not sure this is feasible. If you have any component to recommend, that would be awesome
