[Theme: Sampression Lite] Filter matched posts

Hi.

Thx for your great theme. You did/do a great job. I having some difficulties in changing the multiple filter option, to show the posts the match ONLY the selected categories.

Eg. If I select 2 categories, then I only want to se the posts that match

both

categories and not the post from 1 category + the posts from the other category.

Hope, that you understand what I mean.

I found your note in the header.php, where you write, that you use som of the code from http://isotope.metafizzy.co/docs/filtering.html.

I also found the code as shown below in includes/functions.php.

BUT I just don’t know how and where to start.

Where can I change the code, so I get the BOTH as described here?
http://isotope.metafizzy.co/docs/filtering.html

.metal.transition will show item elements that have BOTH .metal and .transition classes.

Thanks in advance.

Kind regards.
