Hi Shruti,
I don´t think there is a way to filter the displayed classification list. The individual classes are not stored as items, but more as some basic string. So the items don´t use a permission model or similar that you could use as filter. In general, the class structure browser is based on a couple of 20 year codetree files with less options regarding additional features (e.g. ClassStructure.js)
You can restrict can_add based on the selected class, but this will have no influence to the visual appearance of the class list.
You maybe could use a custom dropdown that you fill in dynamically with the classes users are allowed to use. Then update the "real" classification based on the dropdown value. But that´s a lot of additional code for just some visual help.
But that´s just may own POV. If anyone knows more, please let us know!
Can't you intercept the javascript in the client and filter it based on a custom mapping in Aras between the classification values and whatever the criteria is?
