Portfolio filter isn't working the way I expected it to...

Hello

When I click UX in the portfolio header of my new build with your template, no items show up? I have one item with a .pf-ux so when I click UX I would expect that sample to appear but it doesn't display.

What am I doing wrong?

Do I have to build an HTML page that holds only the ux samples? I was hoping the filter functionality would automatically generate a page with all items tagged as .pf-ux

<article class="portfolio-item pf-ux pf-ui">

Nevermind! I think the problem was I didn't capitalize my pf-ux. I changed it to pf-UX and now it works.

Thank you.
