HELLO!
Hello developers! 
I’m trying to recreate the settings system from “The Mimic”. I want the tweens and animations to be 1:1 with the original, but I am stuck making the dropdown menu from the system.
For starters here is what the original looks like:
Here is mine:
As you can probably tell, the major difference between mine and the original is that the dropdown is not as smooth (beside from the missing buttons and sliders).
I wonder how I could make this effect 
I have an idea of how it works, but I can’t think of any solution 
Help would be much appreciated 
Thank you so much 
Have a great one
