The behavior that I meant is that the hidden widget can have multiple values.
<input type="hidden" name="hidden1" value="1">
<input type="hidden" name="hidden1" value="2">
<input type="hidden" name="hidden1" value="3">
I tried this
template::element create formname hidden1 -widget hidden -value 1
template::element create formname hidden1 -widget hidden -value 2
But it will result in an error since the element hidden1 is already defined.
