How to set up a Encyclopedia page with Catchphrase Dictionary on the right side

How can I set up a page which looks like in the following example?
I tryed to generate a template but I dont know how to integrate menue of the encyclopedia and the content it self.
I could only use the link htttps://………..net/enzyklopaedie/ to access the encyclopedia page. But there is the right side different.
I also want to have the overview of tag/ Catchphrase on the right side to display/list all content which has the Catchphrase.

Can someone help me?
