From dependencies I can hide a field. It would be nice to add dependencies not only for visible/hidden status, but to delete fields too (if state is no, then delete text field).
Please imagine that I have a state yes or no and a text field which is hidden when state is no. If I first select yes I could write in the text field everything I want, but then if I select no on state and save, text field will be hidden. But it will have data which are accessible from search.
