Sidebar for the Events Manager

I wanted to have a sidebar on a single events of Events Manager.
Not just a sidebar I wanted to have a dynamic sidebar, it will just replicate on what the sidebar of the events list is using.
Example:
I have two category of events.
And listed each category of events on the page using different sidebar.
So when the user click the sidebar on the events list then go to the single events the sidebar of the single event will be the same on the events list.
Anyone can help me.
Thanks
