What is the variable for having multiple minibuffers?

Question

I remember a while back that I could open a minibuffer within a minibuffer.
But now I can't seem remember what the variable was or if it was package specific.

I'm using Ivy, Swiper, and Counsel.
Does anyone know?

The feature is called (emacs) Recursive Edit, it's disabled by default, you can enable it via

(setq enable-recursive-minibuffers t)

With Recursive Edit enabled, you might also want to enable minibuffer-depth-indicate-mode to indicate current Recursive Edit depth in the minibuffer prompt.

(minibuffer-depth-indicate-mode)
