We've been working for a while on the filter. Finally, the beta version is out. This filter supports filtering by product tags. If you want to support filtering by other criteria, please send an email to support.
How it works:
- Input the product tags on the bundle page
- The tags will be displayed in a drop-down box
- The filter style may not be able to support your theme (too many of them!)
- Only a select box is supported at this moment.
- The filter may not update immediately. This is because updating Shopify metafields is too slow
