Code area directive

The sf-code-area directive marks a text area as a code section and sets its attributes. You use the directive on top of your widget or designer view, so that custom widget code is displayed and styled in a specific way, for example, in the widget designer.

The sf-code-area directive is based on the CodeMirror text editor for code, version 2.18. For more information, see the official website of CodeMirror.

IMPORTANT: When using this directive, make sure you add the the following on top of your view:
  • @using Telerik.Sitefinity.Frontend.Mvc.Helpers;
  • @Html.CodeMirrorScriptReferences()
