To filter the top-right list so it shows only the sub-categories which match the item selected from the top-left requires you to create a tree-model filter.

Rather than try to code that up for you (since I don't know how and what is expected to match), I've posted a complete program which uses a filter: https://openeuphoria.org/pastey/310.wc

Note that you will obtain your search term from the first box rather than from buttons. Otherwise, the code would be the same.
