I’m use to working In Wordpress this shopify thing, is annoyingly weird platform to be working in, can you please point me into a direction where I can change the input field to accept html? I didn’t choose Shopify as my “go to” platform if it weren’...

yeah but, what about an area like for input field for pop up maker? It doesn't even have underline option, seriously did Shopify forgot some us know how to code HTML?
