When you publish or switch to a new theme, you must reinstall Infinite Options in that theme.
App blocks do not transfer between themes.
Until you re-add the Infinite Options block, your options will not appear on your product pages.
Step 1: Open the Theme Editor
From your Shopify admin, go to Online Store → Themes
Click Customize next to your new theme
Step 2: Open a Product Template
At the top of the theme editor, click the dropdown menu
Choose your product template (most stores use the Default product template)
Step 3: Add the Infinite Options Block
In the left sidebar:
Locate the section that contains your product title, price, and variant selector
Select Infinite Options Fields from the Apps tab
If the Infinite Options block does not appear, your theme is not a Shopify 2.0 theme.
Step 4: Position the Block
Drag the Infinite Options Fields block to your desired position.
Most merchants place it:
Below the variant selector
Above the quantity selector
Above the Add to Cart button
Click Save in the top right corner.
Infinite Options is now installed.
You can begin creating Option Sets inside the app.
Re-Add the Dynamic Bundle Price Block (If Using Additional Pricing)
If you use Native Bundling or Product Bundles and want the product price to update when customers select paid options, you must also re-add the Dynamic Bundle Price block.
In the same product template:
Select Dynamic Bundle Price
Position it where the price should appear
If pricing is not updating on the product page, this block is likely missing.
