You may want to apply a specific design to the "Bundles" page or "Mix and Match" page and you may need to create a new template in order not to interfere with the default template of the pages of your shop.
How can I add additional elements to the Bundles or Mix and Match page?
The Bundles and Mix and Match pages use the Default Page template. To add additional elements to these pages, you need to create a new template and assign it to the Bundles or Mix and Match page. This ensures that the changes you make are only applied to these specific pages
Steps to do this:
1- Go to "Online store" > "Theme" > "Customize".
2- From the top menu, go to "Pages" > "Create Template".
3- Create this template based on the "Default page" and choose a name for it.
4- Go to "Online store" > "Pages" > The "Bundles" or "Mix and Match" page.
5- From the "Theme Template", choose the newly created template for the page and save.
Now you can apply the changes that you want to this template in the Shopify theme editor and stay assured that other products and pages that have a different template won't be affected.
