# Subpages ![](../../assets/gifs/create-subpages.gif) ## What Subpages are the second tier macro building blocks of Hubs. They function as a canvas for blocks. They are commonly used to house content based on a specific topic. Subpages can have more subpages nested underneath them, which gives you lots of flexibility to organize your Hub as you see fit. If a subpage has subpages nested inside of it, it will be displayed as a collapsible group in the left sidebar. ### Hubs Architecture Top Down - Pages - Subpages - Blocks - Header and Footer - Blocks ## How ### Create a New Subpage 1.
