In the document library I defined a new column (multi-value) choice field for tagging the document. Than I added a SharePoint Online page --> added the document library web part on page and configured it so that only a special folder will be shown.
Below that web part I want to show related documents with the similar tags. I tried it with the highlight content web part where I can use CAML queries but without success. The problem here is that I cannot set dynamic search terms from my web part above.
Has anybody an idea how I can solve this?
