# Content Lang

toolbars.toolbar-1.content-lang

<table><thead><tr><th width="284">Property Name</th><th width="253.33333333333331">Type</th><th>Default</th></tr></thead><tbody><tr><td>toolbars.toolbar-1.content-lang</td><td>string <mark style="color:red;"><code>format: ISO 639-1</code></mark></td><td>en</td></tr></tbody></table>

This option determines the language used for text rendering and can also affect the text direction (<mark style="color:red;">RTL</mark> or <mark style="color:red;">LTR</mark>) within the editor.

By default, the `toolbars.toolbar-1.content-lang` configuration option is set to "en", indicating English as the default language. However, you can adjust this value to match the desired language code based on the ISO 639-1 format. For example, "en" for English, "fa" for Farsi, "es" for Spanish, and so on.

To configure the language of the editor's content within Toolbar 1, update the value of `toolbars.toolbar-1.content-lang` in the `config/nova-ckeditor.php` file with the desired language code.
