I'm trying to make a connection in overlay from gumroad site , I've seen several sites with that.
gumroad explains how to do it. already tried but this fails me something.
I explain my idea is when I click on an image in wix , the gumroad mode enters the site and has a small cart. very useful for me, very simple.
the only problem I have is that it doesn't go in overlay mode but in a window embebed.
any expert ?
