Hi

I'm struggling with organizing things in a large-scale portal i'm developing

It's obvious for me when it comes to high-level categories but where it get's touchy is in the granularity and the different content types

In this portal, we'll have a few content GROUPS:
News articles
Product reviews
Product updates

Each of these groups, there will be regular blog layouts (text, images ...) or video blogs. I refer to these as content TYPES

I'm trying to structure this so the users can select a CATEGORY then have to ability to filter by content GROUPS, TAGS and even TYPES

Ex:

Business category
- Marketing category
- - CRMs category
- - - Hubspot tag
- - - - News content group ?
- - - - - Blog content type ?
- - - - - Video content type ?
- - - - Reviews content group ?
- - - - - Blog content type ?
- - - - - Video content type ?
- - - - Updates content group ?
- - - - - Blog content type ?
- - - - - Video content type ?

I can see here that Business, Marketing and CRMs should be CATAGORIES (with menu items)

I think Hubspot here should be a TAG in which I will add a tag filter module above the CRM page (maybe have it's one single tag menu item too)

I am not sure now how to go about the content groups and content types ? Once in the HubSpot page (single tag page) for example; I will want users to filter by content group and content type somehow.

I think what I am asking is; can custom fields be used to group different content GROUPS and TYPES like this ?

Logically, I could set all this up 100% as categories but this will get laborious when considering I can have 100's of TAG content. That would mean I would need to create thousands sub categories for my content groups and types (each time I have a new TAG like category, I would need to create about 9 sub categories for it's groups and types) and that's not even counting the related menu items if I want to manage things on a page level for each of these.

Surely there's a better way of doing this ?

Thanks
