I have a Custom Collection Editor and overridden some methods - everything works fine...

BUT I now want to block the up and down buttons, so the User won't be able to move the Collection Items within the Index.

Is there any possibilty by overriding a method so it won't move the collection items?

To make it clear - I do not want to remove the buttons or make them invisible, I just want to block the functionality.

Thank you in advance,
Robert.
