Just in case anyone missed it we have added a dashboard iframe widget to the flows site.
ui-iframe node is a UI widget that can be used to embed an external Web page in a Node-RED dashboard.
The URL of a web page to embed can be specified in the settings menu or by the
url property of an input message.
payload property of the input message specifies data to send to the embedded page using the Web messaging API (postMessage). This allows commands to be sent to the embedded page. This capability may not be all browsers. If data from the embedded web page is received via the Web messaging API, it is output as the
payload value the of the outgoing message.
Several examples are included to import. Hopefully this will be useful. As usual comments welcome.
