This component also makes use of form field styles, which can be customized by the following variables:
- If you can’t reasonably predict a user’s answer to a prompt and there might be wide variability in users’ answers.
- When using another type of input will make answering more difficult. For example, birthdays and other known dates are easier to type in than they are to select from a calendar picker.
- When users want to paste in a response.
- When users are choosing from a specific set of options. Consider checkboxes, radio buttons, or a dropdown in these cases.
- Don't use placeholder text in form fields. Use hint text instead, if you need to provide contextual information.

fieldsetelement. Use the
