Accepting drawing from other group through multiport in

how can i create a group that accepts drawing from another group.I have two groups lets say A and i need to transfer drawing element of group B to A.

yes the process is little strange haha but that worked.thank you so much.

It’s a little bit counter intuitive. In group A (the receiving group) drag a node connector from the top of some node to the multiport in node. This should allow you to make a new input. Move up a level and the group should now have two ports on top.
Use the same process in group B, dag from the bottom of the drawing you want to take out and connect it to the multiport out node, then on the outside of the groups you can connect both.

I find it quite frustrating that you can make a new input or output connection from the outside of a group, but that’s how it works.
