auto-height

Hi,

I can’t get the auto-height on-click/ajax function to work. Can someone point me in the right direction. The iframe is used on this page: https://www.studiotp.nl/hosting-basis/.

The path of the iFrame is direction to a subfolder (e.g. studiotp.nl/bestellen) is this considered cross-domain?

Thanks
