Linking List with Document Library and creating a combined view

Hi

We have a regular committee with agenda topics and accompanying files (slides, excels, ..).

I have now created a list of topics with date, type, results, presenter etc. and a document library with a lookup-column to the topics. So each document belongs to one topic, but a topic can have zero, one or many documents. From the modelling point of view this fits. Attachments to list items would not suffice, because I also want to manage the document library as such (sync, alerts, filter etc...)

I now need a proper, user friendly view that shows all at once. For example:

GroupBy Date, then GroupBy Topic, then all documents (if any).

The problem is that I dont know how to show the many documents that belong to a list item in a view. Is there a way?

The other (workaround) idea is to provide a link (per item) to a preconfigured view (of the document library) that has all documents that belong to this item.

I am relatively new to sharepoint, so bear with me if this is a stupid question or one that has been asked many times before.

Thanks, Sebastian.
