How can I filter specific content to a page template?

I’m evaluating Webflow for our design team at work. We’re about to stand up a CMS for our design system. I thought Webflow might be a good solution. I was able to sell the team on the product but need to get a proof of concept working.

I set up a collection where I have individual pages for the components we will need in the nav. For example a page for Button, Spinners, Selects etc.

The problem I am having:
I made another collection of say Best Practices. I need specific content for Practices for Button, Spinners, Selects. I tried setting up a filter to say if I am on the buttons page show me button best practices. That worked but it shows on every single page no matter what I try. I’ve also tried Multi Reference fields to try to pipe in content but again it pulls in content to every single page.

How can I filter specific content to a page template?

Any help would be much appreciated.

My file is called Filter

I used a CMS collections component
I’m pulling content in from a CMS collection

I would like to customize the page content by filtering or pulling content in from another CMS collection. When I do that it duplicates to every page. I need to filter content to specific pages
