Remove update version dropdown box

onegun

On update mode, there is a dropdown box showing various version on the top right corner, how to hide it?

There is a "get_others" method that is inherited by your module's model. You can set it to return an empty array and that dropdown will not appear:
public function get_others($display_field, $id = NULL, $val_field = NULL) { return array(); }

I think I misunderstood which dropdown you were talking about. What you are seeing it sounds like is the version dropdowns. If the module parameter of "archivable" is set to TRUE (which it is by default), then it will create an archived version after every save.

I did notice that if you previously have it set to TRUE and then set it to FALSE, those older archives would still show up in the dropdown select. I've pushed an update to the develop branch that will simply hide it if that is set to FALSE even if there are older archives.
