In case a label doesn't provide sufficient information for an input field and an additional hint is helpful, when should the hint be available next to (or below) the input field and when should it be hidden behind an info icon?
Four criteria I thought off: - In case the hint exceeds 100 words, use the information icon - In case the hint includes a link to further information, use the information icon - In case the hint relates to an infrequent action and is not intuitive (e.g. Maximum upload size), show text directly - In case the hint is only relevant for novice users, use the information icon
Are these correct and what criteria are missing?
Thanks in advance!
