Shopify code fixes & small design changes needed

I'm a front-end designer and need someone to give me a hand with some code fixes. The following tasks need to be completed on a Shopify dev store: Collections 1. Collection filter on the left-hand side is fixed on user scroll. I need the 'stuckFilter' class to be removed when the filter options are open. All filter options are collapsed when the user visits the page. 2. Show tags (brand, style) on product grids. This will need to be a .js solution editing assets/[login to view URL] as the script is rebuilding product data. Product page 3. Add vertical product thumbnails (instead of horizontal) on product pages - responsive layout (must work on all devices) The work will need to be version controlled and every commit added to 'feature-dev' branch on: [login to view URL] ETA: needs to be completed by tomorrow, 13th Nov Budget: $80
