Portfolio Column Count

Hello,

How do I show more than 4 portfolio items in one row. I know there is a Fullwidth 6 columns page sample installed in my theme but I also wanna add categories to the top and don’t know how to do that? Also Is it possible to show more than 4 category tab on my portfolio page?

And how do I delete the date on portfolio items?Found this in HB forums but did not work for me:

.item-overlay-text span.item-count-text, .item-overlay-text .item-date { display: none; }

Please do answer to all 3 questions above, normally they just answer to one:(

Regards
