That almost worked great!
I have three different searches on the page for three different custom post types. Two of the searches are hidden until the user clicks a button. As the results of these are hidden it was getting a width of 0. If I resized the browser it would recalculate and look correct. So I added the number of columns in manually and it is working now.
I guess this would be fixed in the release version if I was able to enter the width of 33.3333%.
Ideally I’d be able to say add
Desktop – 4 rows of 3 columns
Tablet – 3 rows of 2 columns
Mobile – 4 rows of 1 column
Maybe in a future release 🙂
Thanks for all the help
