Is it possible to limit a container to accepting a specified item only and nothing else without coding ?
( or very simple coding) thank you in advance. Help would be appreciated. I have checked the tutorials but can only find volume limits.

Re my last question on containers all I want is how to use the item for restricting objects put in a container
I want only one particular item allowed.
After if I must enter a script
How do phrase ‘object is bush ‘ in code?
( I am putting a plant into an animal’s manger)
It would be silly if the animal , cart or miscellaneous stuff were put in.

I think you are after something like this:

if (object=bush) {
  msg ("You put the bush into the manager.")
  MoveObject (object, this)
}
else {
  msg ("That doesn't seem like a good idea.")
}
