Hey there Junchol
Unfortunately, we don’t have an easy way to accomplish that. The Photo View uses jQuery Isotope to output the items in a Pinterest-type grid but not in a rigid row-column type grid.
If you’d like to see the script improved, feel free to suggest it as an enhancement at our plugins’ UserVoice page.
This allows others who are interested in that feature to easily voice their support. We frequently review suggestions there to find out which ones are popular, then we implement as many of them as we can.
If you’re wanting Photo View’s sorting or grid/layout customized for your site, I’d guess any customization would need to be done via JavaScript, not CSS. If you need some coding help, you may want to ask your developer or reference our list of known customizers.
Thanks
Courtney 🙂
