Redactor v3 Features Source

The source mode is shown when clicking the HTML icon in the toolbar and lets you see/change the raw HTML source for the content.

Enable source mode

To enable it, make sure "Allow Source Mode" is enabled in the Source section of the configurator, and add html to your toolbar buttons under Toolbar where you want the button to be available.

Syntax highlighting

If desired, you can enable CodeMirror syntax highlighting for easier use of the source. Under the "Source" section of the configurator, make sure "Enable CodeMirror" is enabled.
