Changing resources held by part with a gui event?

[Greendolph]

I am working on a shipping container part and would like to either iterate through a list of resources using a context menu event if it is empty, or if that is not possible instead set a mass limit on what can be stored in the container and have all the resources permanently listed in the parts cfg. Any ideas on how I could go about doing this? I can't find good documentation on it.

Thank you!

You should have a look at how B9 handle it. Its parts can change with the context menu. I think it uses one of Firespitter module to do it.
