Render procedural mesh in editor

I have a script that generates a procedural mesh. It works fine in-game, but is there any way to render the procedural mesh in the editor if this script is attached to a game object in the scene?

I've been trying to find the correct search terms to figure this out myself, but so far I'm failing.

 

I found the answer myself. For anyone else looking for the same information, there is a class attribute [ExecuteInEditorMode] that makes a script run even if you're not in game mode.
