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)?? (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.
