lost "details" slider in the Detail panel of the Edit window

I was using Lightroom to edit some photos.  I think I clicked where/when I shouldn't have and suddenly lost the "details" slider in the Detail panel of the Edit window.  How do I get it back?  Right now in that panel I have "sharpening," "noise reduction," and "color noise reduction," but nothing else.

Click on the 'carrot' icon to expand the other Detail sliders and make them visible-

Got it! Thanks a bunch! I knew it had to be a simple 'click' somewhere -
I just couldn't figure out where.
