Add Reorderable list that contains a label on a custom editor window

Hi there!

I use C#. I have a custom editor window. I would like to add a reorderable list on it so that it is easier to change the order of the items in the list.
I know there is already a class called ReorderableList, but I don't know how to set it up on custom editor windows.

Also the reorderable list should support drag and drop.

How to achieve this?

--- Glad for any kinds of help!
