login form doesn't show up when changing display none to block

Hi,

I want to have tabbed page with client information. I have tabbed this with divs, css, and a little of js. Everything works fine as long as i got static content in it When I try call snippet inside divs, nothing shows up despite I can see it in source.

Any idea why?

Do you have a link or the source code and CSS ?

between divs I got snippet call + tpl
