I am currently designing an ecommerce site that has a fixed primary navigation, but further down the page we have a secondary navigation (Product Specifications, Additional Information, User Reviews) that also need to remain in view for the user as they scroll down.
The secondary navigation will bring the user down to the area of the page where that content lives, but the user still needs to see secondary navigation as they travel down the page. However, we also have the primary navigation that will be fixed.
Having searched and found no results, is having a fixed primary navigation and a secondary navigation (that will live as a pit bar) right below bad practice? Is there a better way to execute this?
