Dave, Using a field as the state field, as opposed to the tags allows you to do this for a two value check
<$checkbox field="selected" checked="a" unchecked ="b"> A?</$checkbox> <$checkbox field="selected" checked="b" unchecked ="a"> B?</$checkbox> You do not need two values 0 and 1 and 0 and 1 if they are intimately linked such as "1 and 0" OR "0 and 1" Or <$checkbox field="selected" checked="left" unchecked ="right"> Left?</$checkbox> <$checkbox field="selected" checked="right" unchecked ="left"> Right?</$checkbox> this kind of logical selection is is often referred to as "radio buttons". So see this https://tiddlywiki.com/#RadioWidget Also with left and right being the choice you could use the range widget, in this case with a neither left or right https://tiddlywiki.com/#RangeWidget <$range field="lorr" min="-1" max="1" default="0" increment="1"/> {{!!lorr}} There are many ways to do this.
