Can we create filters in webflow by pricing , size, colour etc?
No. Faceted search is not currently available. You have no hooks into elasticearch. You can only choose what is indexed.
Is there a way around ?
I can only think of one possibility. Export all your CMS data, into a JSON file, then use a third party search engine like Algolia.com, and push that data up and then display it via their API where you want. I have done similar before.
Thank you for the response. Would i have to keep updating the both the cms when i make changes in one or will it be automated?
Two options currently exist: You export data via the WF API, or CSV and import it into Algolia, or you bridge the two using the API provided by both with a custom app running on a separate server. The first is manual, the second a batch. Neither is real time. Unless you are a coder or have a team, the latter would require paying for development. Maybe in the future a Zapier integration will exist with Algolia.
Magento has faceted search and now has an integration to Algolia. There are other solutions you can research.
Here is a straightforward tutorial showing how Isotope can be used to set up faceted navigation using Webflow CMS: https://youtu.be/tLS3I-lXWGY
