Three-valued / Ternary logic in sugar

Question

I want to have a data-type for 3 values: TRUE FALSE UNKNOWN Boolean fields only cover true/false. Is there a way to activate "unknown"? Workaround would be a dropdown. Thanks for input and ideas!

Hi G&uuml;nter, In 7.7 you can create any field type you want by code, I can recommend the following documentation on it: http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.7/User_Interface/Fields/Creating_Custo&hellip; I'm not sure about your use case, if a fully custom field type is not necessarily needed I would go for either a radio button field or dropdown field like you suggested.
