Dependent Multi Prefix System

[alfaNova]

Prefixes are really usefull function to categorize threads, resources and simplifying forums. I would like to recommend implementing a hierarchical or dependent prefix system that allows users to select a primary prefix, which then determines the availability of a secondary prefix. This feature is particularly useful for multilingual forums, document categorization, and structured classification.

Use Cases:

1. Multilingual Forums:
   
   • Users can first select a category prefix (e.g., "Standard") and then refine it with a language prefix (e.g., "Spanish").
   • Example: Standard > Spanish, Book > Turkish
     
2. Document Classification:
   • Users can classify documents by type and then by status.
   • Example: Regulation > Withdrawn, Standard > Superseded
     
3. Broad Categorization Needs:
   • Users dealing with large datasets or knowledge bases can use dependent prefixes for better organization.

Feature Specifications:

1. Primary Prefix Selection:
   • A mandatory or optional selection depending on forum settings.
   • Determines the context of the content.
     
2. Secondary Prefix Selection:
   • Becomes available only after a primary prefix is chosen.
   • Can also be set as mandatory or optional.
   • Secondary prefix options are filtered based on the primary prefix.
     
3. Prefix Dependency Management:
   • Admins can define relationships between primary and secondary prefixes.
   • Some secondary prefixes can be exclusive to certain primary prefixes.
     
4. User Experience & UI:
   • Dropdown or selection-based system.
   • Secondary prefix dropdown activates dynamically based on primary prefix selection.
     
5. Filtering & Searching:
   • Users can filter posts by primary or secondary prefixes.
   • Improves search functionality by refining results based on hierarchical prefixes.
   • An additional prefix menu can be beneficial.

A dependent prefix system will significantly enhance categorization, filtering, and search functionality in forums and document repositories. This feature provides greater clarity and organization, especially for multilingual or technical communities.

I hope the XenForo team considers implementing this feature in future versions.
