Hello,

I would like to divide the forum into three parts. The page has a main subject, `subjectA`, which I created another off-category `subjectB` next to. For this, I thought that a three-way switch should be made in the header or in some other central location. By default, the switch would be in the middle position, which would mean that both `subjectA` and `subjectB` of the page would be visible. If the user moves the switch in the direction of `subjectA`, then `subjectB` would not be visible, if in the direction of `subjectB`, then `subjectA` would not be visible. We could handle these with groups and category permissions.

If user select the `subjectA` then it adds the user automatically to a group `groupA` which adds some permissions to `subjectB` categories to mute.

I try to figure out how to make a CTA button or a toggle to join or leave a group by clicking on it. But unfortunately I didn’t find any way. Is this possible somehow? 🙂

This project is for to add the ability to users to quickly and easily filter the content from the two main subjects.

Any idea or advice would be appreciated! Thanks 🙂

For an alternative approach you could have a look at the [Epic Games Dev Community Forums](https://forums.unrealengine.com). They use four global filters and I believe you only need the [GitHub - discourse/discourse-global-filter · GitHub](https://github.com/discourse/discourse-global-filter) plugin to implement a similar setup.

Thanks @manuel, This looks great. For the first look if I see it correctly this plugin works something like [Using query strings to filter topic views](https://meta.discourse.org/t/use-query-strings-to-filter-topic-views/248224) with tags but it keeps the string while user navigates on the page. I have to rethink the structure of my forum. 😅 Thanks again I’ll give it a try. 🙂
