I need a developer who can help me with a responsive iframe widget.
I want to use a page of my WordPress website as a widget, by embedding it as an iframe on external websites. However, the content of my page is dynamic in height (there is an expandable acordion on the page). That's why I need the height of the iframe to adjust accordingly when the content increases in height.
I know postMessage() allows cross-origin communication so I can send the height of the source to the external website iframe code. But unfortunately I cant seem to get it to work..
An example of the solution (I think) can be found here: [url removed, login to view]
Who can help??
