Events and posts style

Hi,

I would like to have the events form the Tribe Events calendar and posts form selected categories appear under the same menu.
Because Events and posts have their own categories, I can not create the menu based on both.
For example, when I add a post under the post’s “parties” category, and a new event under the events’ “parties” category, I would like to have them appear on the same page, in chronological order with the same style.
The site is http://www.educarewaldorf.it
All the events and posts appear correctly on the home page, but I can’t figure out how to use the same styles and ordering on another page.
Thank you for your help, great place, great helpful people here.
