Dear Community
My current checkout layout is left and I want to change the layout to this one in the right picture:
Hi @admintb
Can you kindly share your store link (with the password, if any) with us? We will check it and suggest you a solution if possible.
@BSS-Commerce Its open now
@BSS-Commerce Can you do that? 
Hi @admintb
This is Noah from PageFly - Shopify Page Builder App
Regards your concern, I’m so sorry to say but currently, Shopify is strict on the Checkout Page, and only available for editing if the Shopify Plan is Shopify Plus.
If not there’s no way to change and edit the layout of the Checkout Page.
Howerver you Navigate to Shopify Settings > Checkout. There will be options for you to adjust some small things in the fields
Hope this can help you solve the issue
Best regards,
Noah | PageFly
