A possible parameter is state with value one of [autocollapse, collapsed, expanded, plain, off]
where collapsed/expanded tells the initial collapse state controlled by the hide button, and plain/off is like collapsed/expanded but without hide button and therefore fixed for the user.
Example: {{Kollektivtransportforvaltere i Norge|state=collapsed}}
