Is it no longer possible to get the cart into a side box

In 135 it was in a side box but I cannot seem to find out how to do this with 2 0 12

Has the option vanished or is there some way of achieving it

I’m trying to find out how. Is it not supported anymore?

It’s not a default setting or option in 2.x. There are at least two user supplied methods for doing this though. Run a forum search for some terms relating to it and you should find them.
