I want to use an addon which is only available for Joomla and Wordpress on a site running concrete5. Since I prefer keeping concrete5 I tried the block "dynamic iFrame" to adjust the size of the block.
But the problem is the iFrame url must be the same domain, sub domains dont work to auto adjust the block size to integrates seemingless in the site.
So my first thought was to install Joomla in a subdirectory of the concrete5 directory but Iam not sure if this is the best practice to solve such problem.

Anyone got some ideas? Thanks in advance.
