# 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}

Extend the EXT:form configuration:

**EXT:my_sitepackage/Configuration/TypoScript/setup.typoscript**

```typoscript
plugin.tx_form {
  settings {
    yamlConfigurations {
      # register your own additional configuration
      # choose a number higher than 10 (10 is reserved)
      100 = EXT:my_sitepackage/Configuration/Form/CustomFormSetup.yaml
    }
  }
}

```

Redefine the backend input in the extended YAML:

**EXT:my_sitepackage/Configuration/Form/CustomFormSetup.yaml**

```yaml
prototypes:
  standard:
    formElementsDefinition:
      Text:
        formEditor:
          editors:
            600:
              selectOptions:
                # Choose an index that is not in use yet
                12345:
                  value: 'cc-name'
                  label: 'cc-name - Full name as given on the payment instrument'

```
