The plugin is buggy and lots of features don't work. I messaged support and they are not helpful or friendly at all. Options that should be there aren't. You're better off using another grid. I've been using essential grid for years and never had a problem. I thought I would try something new, but it's not worth the hassle back and fourth with a support team that isn't passionate about the products they support.

After your 6 replies and two ratings in less than an hour... without having read the documentation nor followed my advices.. well.. probably Essential Grid is what you deserve!
(but for some reason you purchased another product :P )
