I'm not sure I'm understanding your question clearly - Could you please rephrase it?
If you're trying to remove a module container, there is a "Display Container" checkbox under settings which allows you to toggle the displaying of a container or not. Note that you'll need to be logged in as an administrator to do this and you'll have to log out in order to see that it works without the container (admin would still see the default container)..
If you're trying to do this conditionally, then this would require some coding to basically grab the container and make the visible flag to be false...

If you still want it to collapse and expand you can create a blank skin where the border is set to 0 don't add any colors and put in all the tokens. Then just change the container to the blank one for that module.
