Drop-down list for materials in revit

Hi!
I’m currently working on my graduation project in revit and need help. I’ve created a shared parameter in revit to give every material different CO2 values, and I was thinking about using dynamo to create a drop-down list for every CO2 value. For example If I choose to use concrete I can look at the different CO2 values that concrete has cog then choose one of them. As I understood I have to use dynamo to make a drop-down list, but I’ve never used dynamo before and would really appreciate it if anyone can help me.
Thank you

i recommend to use keyschedules first, than you can check later for a dynamo solution…

If you’re wanting to learn Dynamo, the primer is the best place to start.

I tried to use key schedule, but I don’t know how to put it in a material takeoff schedule and associate it only to materials
