hi
checked again and I am sure it doest'n work...
in reproduction component
I ve saved twice "togglabe"
the view name with "T" letter is checked to be togglable in builder,
the result in sandbox is easy to recheck.
this is not urgent feature but should be noticed,
in some other component I was switching the order of adding
togglabe collections and in the end I ve 3 collection wiht togglabe/nottogglabe button like I needed.
I write all minor bugs down but,
don't want to flood you with minor impact stuff on forum,
some day ill send that privately.
