In more than one occasion you need to put a module inside an article or a bigger module. Well, here's how:
Create the module and indicate to the container a non existent name, so that the module is published but not visible.
Edit the item and add between braces loadposition xxx,where xxx is name of the container of step 1
There is another method:
Edit the article and place loadmodule yyy also between brackets. Where yyy is the name of the module, it does not necessarily have to be published in an unseen container. This method does not work for all modules.
