I'm assisting the design team to create an e-commerce website. The
website has a few hundred items, with the typical product-category left
navigation bar in the home page and listings page, with 10 to 20
categories and probably subcategories. Also typical, when browsing
categories with that left navbar, you get the usual "you are here"
visual feedback in it.
The website also has a product search input box on every page.
Designers want to have the left category navbar on the Search results
page (SRP), but I'm not sure it'll be useful there.
I'm trying to find arguments for and against using that categories
navbar in the search results page so I can help make a decision.
