Discussion List in editor inspector dropdown

Hello, I'm trying to find a way to create in an inspector script, a drop-down, which will contain the elements of a list in the editor, but I'm having a little trouble finding how to do it :/

 

Check out this thread. It includes a tutorial/code on custom inspector drawer for drop-down behavior, among other things. It's a bit advanced, but the custom drawer, the part you're interested in, is as simple as it can be. (It's under QuasiEnumDrawer button.) If you're still unsure about any of it, just ask, and I can walk you through it.

Edit:
You can also download the latest version of the entire source code in this post, for further inspection.

 

Thank you that's great, I just have a little headache now xD
