By the end of this the Atlas Bundler block will be on your product template and your bundle offers will be visible to customers. It takes a minute or two. You need theme editing permission in Shopify, and at least one bundle already created, though you can add the block first.
Unlike the two Atlas app embeds, the Bundler is an app block: it has to be placed on your product template rather than simply switched on.
In this article:
Step 1: Start from Atlas
Open your Atlas dashboard.
Find the Theme extensions card.
If
Atlas BundlershowsNot added, selectAdd to theme.
Shopify's theme editor opens on your product template with the block staged for adding.
ℹ️ Worth understanding before you start: the discount behind a bundle is created as soon as you save the bundle. It is live on your store whether or not the block is on your product page. Adding the block is what makes the offer visible, not what makes it work.
ℹ️ That last sentence explains a genuine oddity. Your bundle discounts exist in Shopify as soon as the bundle is active, whether or not the block is on your theme. Adding the block is what makes the offer visible so customers can choose it.
Step 2: Position the block
The block appears in the product template's section list. Drag it to where you want the offers to appear.
💡 Place it directly above the add to cart button. Customers should see the offers before they decide how many to buy, and anything below the button is often missed entirely.
Step 3: Save
Select Save in the theme editor. Nothing is applied until you do.
This is the step most often missed. If the dashboard still shows Not added after you have been through the theme editor, this is almost certainly why.
Step 4: Confirm it worked
Return to Atlas and check the Theme extensions card.
Atlas Bundlershould showAdded.Open a product with an active bundle on your storefront.
Confirm the offers appear where you placed them.
Check on a phone as well as a desktop.
Checking it is on the right template
The Atlas Bundler block works on any product template, including the product pages Atlas generates. What it cannot do is appear on a template it was never added to.
Many stores have more than one product template. Add to theme opens one of them for you, preferring your standard product template because that is the one most products use. If the products you are bundling sit on a different template, the block went somewhere they will never see it, and you add it to theirs as well.
To check:
In your Shopify admin, open Products and select a product that should show a bundle.
Look at Theme template in the right-hand column of the product page.
If it is not the template
Add to themeopened, open that one in the theme editor and add the Atlas Bundler block there too.
⚠️ The block must be present on every product template your bundled products use. There is no limit on how many templates you add it to, and adding it to one does nothing for products on another.
Adding it manually
If Add to theme does not work, or you are adding the block to a second template:
Go to Online Store, then Themes, and select Customize.
Use the template selector at the top and choose the product template you need.
Select Add block in the main product section.
Under Apps, choose
Atlas Bundler.Drag it into position.
Select Save.
If your bundles still do not show
Work through Why aren't my bundles showing on my store?, which covers the block, the bundle's status, product targeting, and the Online Store publication requirement in order.
