Make input lists draw from actual lists

I am trying to make a system for lists like scratch's.

I would like the input list to just show variables that are known to be lists. For this I've created a list of known lists that I add to whenever I create a list. I also need to be able to have this function to be able to make everything work in the list adding system.

So, question: can I make a list of inputs draw from an existing list/variable?

Unfortunately the only way is using javascript.

ok, thanks

how do I use this?

You need to load the project in and enable JavaScript extensions


Its a shame they got clobbered by the JS restriction - I was really proud of them!

I meant, how do I use this with my block?

Sorry, I don't know that. That's a lot of information on the thread so could be worth a read
