Gpii 726

http://issues.gpii.net/browse/GPII-726
This looks like a duplicate of the function used for the other more/less toggle. We should try to only have one instance of the function that is used twice. Is there a base grade that contains more/less, if so we should put this function there. If not, we may want to consider making one, or finding some other suitable place to put the common function.
