portafolio grid ajax and functionality likes "accordion"

Hello, I love the portfolio grid with AJAX functionality.

I would like you to make a click on the image and opens new layer, it appears only section of content.

Super useful meeting this functionality because it is like an “accordion” but much more powerful.

I tried with

.page-id-147 .av_table_col .first .portfolio-preview-image { display: none; }

but don’t works.

The modification would have to be for just one page, not the entire site.

Best regards!!

Xavier.
