on/off switch for Fieldset (page)

[Matze]

Hi,

for items in repeaters and matrix there is this little on/off switch to temporarily turn them off and on. Are there any options like this for single fields too? Espcaially for fieldset (page)? Or is there maybe a module for this? (couldnt find, but maybe i havent used the right keywords).

Of course i could add a checkbox myself and code the exception but maybe there is a more elegant solution for this?

Thx!
