The editor field.

The editor field uses the Cloud 9 ACE Editor plugin to render an inline editor that supports a wide array of textual content types. The editor provides a number of very powerful features and allows for the creation and modification of markup and code such as HTML, JavaScript, Java and other languages.


JSON Schema Type(s)string
Field Typeeditor

focuscheckboxtrueIf true, the initial focus for the form will be set to the first child element (usually the first field in the form). If a field name or path is provided, then the specified child field will receive focus. For example, you might set focus to 'name' (selecting the 'name' field) or you might set it to 'client/name' which picks the 'name' field on the 'client' object.

The Editor field requires the Cloud 9 ACE Editor to be loaded ahead of its use.

Be sure to load lib/ace/src-min-noconflict/ace.js before rendering your forms. You can download ACE from the ACE project on GitHub.

Example 1: Simple Configuration

You can instantiate an editor field by simply setting the type option to editor. The editor field produces text so make sure that the field type into which the editor places its results is a text field.

Example 2: Using a different theme ("twilight")

The ACE editor supports a number of out-of-the-box themes. You can specify these themes using the options configuration. Here, we configure the twilight theme. We also explicitly set the width and the height of the editor.

Example 3: Editing a different content type (HTML)

The ACE editor also lets you configure for the editing different types of content. By default, the editor configures itself to edit ace/mode/javascript which is the plugin for JavaScript files. Here, we configure the editor to edit HTML files by setting aceMode to ace/mode/html.

We also set the aceFitContentHeight option to true to tell the editor to automatically resize the height to fit its contents.

Example 4: Customizing the editor

The editor can be customized programmatically using the ACE editor API. You can grab the reference to the editor control via the postRender callback.

Take a look at ACE How To Guide for some good starting points on API customization.

Example 5: Multiple editors

You can use Alpaca to instantiate multiple editors if you'd like. Here we instantiate three editors - one for JavaScript, one for CSS and one for HTML. When the JavaScript editor's value changes, we update the HTML editor.

Example 6: Editing Markdown

The editor can be used to edit a variety of formats including markdown.
