# Constant Editor {#constant-editor}

<!-- TODO: no Markdown rendering for "versionchanged" -->

Site sets have been introduced. The
settings of the site set
superseded using TypoScript constants. Using TypoScript constants is
still possible for compatibility reasons.

> [!TIP]
> If [Site sets](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/SiteHandling/SiteSets/Index.html#site-sets) are used, the constant editor might be disabled. You can then edit
> the settings in the [Settings editor](https://docs.typo3.org/permalink/typo3/cms-fluid-styled-content:settings-editor@main).

1.  The **Constant Editor** can be found in the
    **Sites > TypoScript** module.
1.  Select the page in the page tree which contains the root Typoscript record
    of your website.
1.  Select **Constant Editor** in the dropdown at the top of the
    **Sites > TypoScript** module.
1.  In the dropdown list select the category **CONTENT**.
1.  This will give you a list with all the constants of this extension.
    All constants are described and can be edited by clicking the pencil in
    front of the current value or by editing the available field.
1.  Do not forget to save the new values. The new values will be stored in the
    "Constants" field of the root template of your website.

> [!NOTE]
> If you use the **Constant Editor** the configuration gets written
> to the database and cannot be kept under version control. You can cut all
> values from the constants field of the root TypoScript record and move them
> to a file in your site package extension. This way you can keep the values
> under version control.
