title: Joomla - Categories and sub-categories calendar
body: <p>I am new to joomla, and I was wondering if somebody could recommend me a plugin for a calendar that support events of a certain categories. Basically what I want to be able to do is the following:</p>
  
  <p>I register several events of some category. For some events I register them as being of categories A and B. Now, in the calendar, I choose the filter category A. It gives me 10 results. Now, I want to apply another filter (category B) over this last set, in order to show me events of A and B.
  This seems so trivial for me when not considering that I am doing this with JOOMLA, since I am using it for the first time. But with JOOMLA I have nooo idea how to start! Please help?</p>
  
  <p>Cheers</p>
