Hi there, I'm brand new to Shopify, and despite being reasonably web saavy, I'm really struggling to make my shop look the way I want it to. I appreciate any help you can offer!
My main requirement is that I find a way to allow shoppers to intuitively sort through my offerings and find what they are looking for. I'm open to changing themes, tinkering with code, changing my approach from using collections, etc.
Thanks in advance!
I believe you're moving in the right direction. Supply actually allows filtering your collections on multiple criteria (explained here, click on Product tips).
This kind of filtering is only available in Supply theme (if you're looking at free themes), but can be added to any theme by editing the code, many paid themes include similar functionality too.
