100% iframe height won't work
You would expect that if you inserted the value 100% for height, that would give you a dynamic resizing. However this is not the case.
This will only give you an iframe with a static height of about 150px.
1. Copy the file components/com_wrapper/views/wrapper/tmpl/default.php to
2. Open the file templates/your_template/html/com_wrapper/wrapper/default.php
3. Replace the function iFrameHeight() with the new function below:
With this new function the iframe height will be dynamically resized and take the size of the wrapped page.
Did this work out for you or did you experience any problems?
