Putting a box in a box

[amith]

Can anyone help me with vizard code ,where a use tries to grab a box and place in horizontally into one of 2 empty hollow boxes .after doing so the box remains inside the hollow box.But if he puts it into another box it will not stay and fall down.

Thanks a million for the help in advance

You can use physics and disable physics on the node when it's placed inside one of the boxes so it does not fall.
