I've used many different container solutions in the past, including FluidTYPO3's FCEs, DCE, gridelements and some more.
I primarily use the functionality of providing container elements that lets the backend user nest content elements in the page module.
But what I haven't seen so far is a solution with core functionality. Shouldn't it be possible to provide container elements via FSC? Does anyone know how to solve e.g. a two-column container element?
Thanks for your help!
