Ok, this is what I found.  My problem is a little different.

 

1) The menu params are grey if you only have one category selected, if you select more than one they will turn on.  But this wasn't really what I wanted and changed the layout significantly.

 

2) My problem was due to the fact that I had nested categories.  I solved my problem with the Sub Category ordering option.  Found on the Category View Options panel.

 

 

 

excellent. thinking about it, that would have worked for me too
