Modify Value List using GH Python

Hi All,

any Python coder is able to assist why can’t I select items from the Value List(Material Section)??

GHPython_Value_List.gh (4.7 KB)

That’s because you are setting your list in code. So as soon as you select something from the second list, it will re-run your python code and reset that list. You will need to make that part of the code only work when the first list is being changed.
