list-field with no duplicates allowed?

[joemienko]

Is it possible to easily prevent the entry of duplicates in a list-field?

For example, a list could contain {dog, cat, fish}...

But not {dog, dog, cat, fish}.

Thanks, for any help you can provide, and thanks for an awesome library!

Yeah, this is a nice feature and I've wanted to add it. For now, if you are looking to implement this for just a list of strings then you can use the SelectField with the multiple property set to true.
