This plugin is broken.

I just tested this plugin for a whole day. Please do not use it.
This plugin has multiple issues.

First: the filter plugin overrides the original classes, so the animations on hover do not work nor the picture preview (there are already multiple threads on the support page).

Second: The filter plugin sets a static width to the container. So if you resize the page after filtering, the responsive design is broken.

Third: the floats in my example were totally out of order, so I had to set it up as inline-blocks, so it would look good

fourth: when clicking repeatedly on the All- filter button, the items move a little bit upwards and downwards, which is even visible in the tutorial video and destroys the professional feeling.

Also a main feature is missing: You can only create one portfolio.

Please do not use this plugin.
