What type of requirements does the site structure belong to?

Question

Analytics

I'm trying to use the requirements specification template from the book "Software Requirements Development" by Carl Vigers, the book describes the following types of requirements:

• Business Requirements
  
• Business rules
  
• Custom Requirements
  
• quality attributes
  
• Functional requirements
  
• External interfaces
  
• Restrictions
  

What type of requirements can be attributed to the structure of the site, and navigation on the site (menu behavior).
Thank you.

Answer 1

Depending on what structure, in general terms, I would attribute it to "Functional requirements", and if this is the structure of some blocks on the pages, then it can fall under "External interfaces" and under "User requirements"
