Hi, I'm trying to create a sortable portafolio like this one http://royale.dzsthemes.net/sortable-portfolio/ but so far I haven't be able to create it.

I have created the categories, the portafolio items, the portafolio page, but I don't know who to make them interact. The instructions in the read me document are not clear enough for me and the demo content didn't have that kind of portafolio included or at least it didn't show up.

Could you please give me the instructions to create a portafolio like this? http://royale.dzsthemes.net/sortable-portfolio/
