Hi
At the risk of hijacking all your posts ;)
....
Modal
open-seb-one-modal-position-in-modal
Hidden
This is a position that is rendered and hidden by css.
Clear
This position is not rendered
Sometimes you want to use a fields value but not have it visible.
Depending on what it is you are doing you could use hidden or clear.
Trial and error to work out which as far as I am concerned
