# Hidden Field

## What does it do?

- **General:** It could be useful to send some values within the form, that should not be displayed in frontend. Use a hidden field for this.
- **Prefill:** This field can be prefilled from FlexForm, TypoScript, GET/Post-Params or from FE_User table.

## Frontend Output Example

Because it is "hidden", there is no visible frontend output :)
