# Autocomplete {#concepts-autocomplete}

The **Autocomplete** select in the form editor can be used to
define `autocomplete` properties for input fields. This extension
predefines the most common of the input purposes that are widely
recognized by assistive technologies and
[recommended by the W3C](https://www.w3.org/TR/WCAG21/#input-purposes). The
HTML standard allows arbitrary values.

If you need to provide additional fields, you can reconfigure the autocomplete
field with additional select options:

## Add Autocomplete options to the backend editor {#concepts-autocomplete-add-options}

Create a form set in your extension and add a `config.yaml` with the
additional autocomplete options. The file is auto-discovered — no PHP or
TypoScript registration is required.

**Required directory layout**
