need help to implement "event list" content type

[habi]

for a customer I have to implement an event list like the example below.
to do's:
- add item in pop up menu
- add file in include/inc_tmpl/content/
- update db entry after form was sent
would like in the admin seperate input fields and serialize it to integrate it in article_text field so I don't have to extend the db

any experience in doing that?
