If you want to create a page with a fillable contact form, you will need to modify the template your current contact page is using.
- From your Shopify Admin, choose Online Store > Pages.
- Click into the page you want to include the fillable contact form.
- In the right-hand sidebar under the Template heading, choose Page.Contact.
The theme must be published in order for the Page.Contact template to appear in the drop-down.
