I know and if someone can find me a way to do it without JS, that would be even better.

What i am looking for is somehow described here: http://www.mozilla.org/xpfe/checkboxSpec.html & http://www.mozilla.org/xpfe/xptoolkit/checkboxes.html

What i am trying to build is a search page. On this page i have many yes/no fields, which i would like to be selected with a checkbox.

For a search page you can have however 3 possible options:
- I am looking for rows where the value is 'OFF' for that field.
- I am looking for rows where the value is 'ON' for that field.
- I don't care what the value is for that field.

See my dilemma. I could use a radiogroup, but that would take a lot more space on the UI, and looks less nice.

In Client/Server software you see a lot of times checkboxes that are either Empty (off), Marked (On) or Greyout-Marked (mixed state).
