- Supports the following options:
| Option | Type | Description |

iframeAttributes: {
classString: 'iframe-noborder full-height etc' // mapped to 'class'
id: 'one-and-only-iframe',
'data-foo': 'bar'
},
styleString: 'body { color: #ff0000; }',
styleLink: 'styles/iframe.css', // an array of URLs is also acceptable
content: '<h1>Sample Content</h1><p>No need to call update()</p>'
};
var iframe = RW.create(container, options);RW.update(HTMLIFrameElement iframe, String contents)
