I have following situation: in category view I have items that have some text and/or image gallery.

Right now I'm showing just titles with link to item details view.

I would like to achieve following:


For the items that have only introtext and no gallery I would like to add an option, that if you click on the title, you aren't redirected to the item details page, instead only introtext shows under item title (toggle effect or similar).
If the item has introtext and gallery, click on the item title redirects you to the item details page.

So basically I need to add PHP condition in category_item.php, but here I would need some help and guidance.

 

Any ideas what would be the smoothest way to achieve this?
