Isotope is a nice script to organize and filter your portfolio or gallery item with some cool effects and functionality like masonry layout support. Peoples are using Isotope very often and I am too on my Projects. It's may For non-commercial, personal, or open source projects and applications, see License. But on the isotope version 2, I was facing responsive masonry issue and also sometimes appear problem. it was very fine and responsive with the old version.
Well, then I mix it up the old responsive functionality with the new one and yes the masonry Isotope is also working fine
