I have set up the mainnav to span9 with span3 items to the right. When it squeezes in for tablet and xtablet things overlap, so I was wanting to turn the span3 positions off and then turn them on above. I have that set up right, but I want to change the span of mainnav from span9 to span12.
I went to the ini and did this.
but it's not working. any ideas?
