how to overcome "Unexpected value is not accepted" validation on form submission

Vote:
 

Hey Everyone,

I am making a custom optionItem element and would like to pass a value and an email as the value, like so...
<option value="<%: item.ValueAndEmail %>" <%= selectedString %> <%= defaultSelectedString %> data-f-datainput><%: item.Caption %></option>

The problem is, validation does not like this and I get the following message:  "Unexpected value is not accepted".

How can I get around this?

Hi,

Your selected option value submitting to serverside must be one of the pre-configured values in EditMode. Otherwise, the above message is thrown.
