ᐅ Door and concealed drawer

A warm hello to the forum,

I want to install a concealed drawer inside a wall cabinet with a door. Does anyone know how far the doors need to be opened to pull out the drawer?

And regarding the horizontal wall cabinets: can they be opened and closed using push-to-open mechanisms?

You will need 153° hinges for this, just like with the base or tall cabinet. A push-to-open mechanism should work.
