     * Helper control is a bit different than the others, it must be always visible:
     *   -  Labels and instructions must always accompany forms and are persistent.
     *   -  The recommendation here is to always have helper text or anything instructions visible.
     *   -  The expectation is to have error text + helper text in the errored state. this way all users will have the helper text information always available.
