I'm using magento 2 and I'm trying to get the visual swatches (color, size..) on the sidebar, on the caterogy pages. I've got the visual swatches for on the product page , but on the sidebar is just text..
go to admin,
Stores -> Attribute -> Product
Go to Color Attribute, click on that,
Catalog Input Type for Store Owner value to
Visual swatch from dropdown.
Same process for
size attribute and run indexing command.
Just go to Admin -> Stores -> Attribute -> Product -> Color(Attribute),
Change Catalog Input Type for Store Owner to Visual swatch and add Swatch Colors...
Go on Storefront Properties tab. Click on dropdown Use in Layer Navigation select Filterable (with results).
Do not forget to clear the cache and make reindex.
Good luck! :)
