dynamic hight also possible?

Of course. This is one of the main features of the plugin.

Please see here for a working demo:

With a simple iframe it is possible if both pages are on the same domain. See my demo.

If they are not on the same domain you need to use the external workaround. For this you need to be able to add one line of Javascript to the page in the iframe. Because the height needs to be send to the parent. A working example is here:

You will not find a simpler way.

Same domain: simple shortcode
Remote domain: shortcode + one line on Javascipt in the remote domain.
