You guys right. My bad. That mixitup demo in livehelper page is actually made for this post Need help creating a portfolio gallery area with sorting function The original site is https://mixitup.kunkalabs.com/.
So, @Mordi_Levi. This mixitup example is might not what you looking for but if it is and you need a help how to make it ask anything for more detail explanation I’d be glad to help for sure.
But for now, beside its elements and properties you can see from its public link, I linked mixitup js in Custom Code settings before /body tag as well as a small script to ‘activate’ it. Since I have a trouble to link it from github directly I copied it and put it on my google drive.

@cyberdave @Mogeek I always forget that the read only preview link does not allow us to look at custom code settings. I wish webflow will allow it in the future.
