hello how can i make a customer fill out a form on my shopify store and submit
Hi @veekay_hair ,
You can create a popup in Shopify with code
First of all, from your Shopify Admin, navigate to the Online store, go for Themes and choose the Customize button.
However, everything will be easier for you while creating a popup by Avada Apps.

I hope this helps.
