Need to shows the group alone in the drop down list

In the Item master I have tree with different parents and childs. In the given link the label of item master with tree. When i choosing the gorup then the only group child should be shown in the drop down box. but now all the parents and childs are come in the dropdown box.

I think for Item Group and Territory you can transact against groups or nodes. Don’t remember why we chose this design. Maybe we can make this a setting and remove it in future updates.

Can you add this to GitHub as an issue.
