Custom field Boolean how to setup this?

[ptrouw]

I tried all options available within a custom field. I am trying to get an Boolean custom field, with only 2 values ON/OFF as radiolist.
How can you setup this? I can't find it in forum or on the web.

I tried with "Is a list" selected, and values on;off. It tried it without a list and with values, etc. I think I tried all combinations.
Any idea on getting this to work with Boolean option?
