Comment 5 for bug 1589872

Nikolay, Fuel UI doesn't display hidden settings (see #4 step from the bug description).
To check if setting or setting section is hidden, UI code processes its restrictions attribute:

https://github.com/openstack/fuel-web/blob/stable/mitaka/nailgun/nailgun/fixtures/openstack.yaml#L946-L949

Here you can see that the whole section has a restriction. And section settings should not be validated if any restriction is satisfied (no matter what action it has: 'disable' or 'hide'). Satisfied restriction means that the setting/section isn't active.
