How do I track form field abandonment?

As a Shopify store owner, I'm constantly battling with form conversion rates. Every abandoned form feels like money slipping through my fingers. I've noticed that customers start filling out checkout or contact forms, but then mysteriously disappear. It's driving me crazy! Sometimes they'll add items to cart, begin the checkout process, and then – poof – they're gone. I know these drop-offs are costing me serious revenue, but I've been struggling to understand exactly where and why customers are losing interest. Is it a specific field that's too complicated? Are there technical issues preventing smooth form completion? I need a way to track these micro-moments of friction, to understand precisely where potential customers are getting stuck. Without this insight, I'm basically shooting in the dark, trying to improve my conversion funnel with zero visibility into what's actually happening during the customer journey.
