Before Infinite Options can display custom fields on your product pages, you must add the Infinite Options Fields block to your theme.
This only needs to be done once per theme.
Step 1: Open the Theme Editor
From your Shopify admin:
Go to Online Store → Themes
Click Customize next to your active theme
Step 2: Open a Product Template
At the top of the theme editor:
Choose your product template
Most stores use the Default product template
This template controls how your product pages display.
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 you do not see the Infinite Options block, your theme is not a Shopify 2.0 theme.
Step 4: Position the Block
Drag the Infinite Options Fields block to where you want your options to appear.
Most merchants place it:
Below the variant selector
Above the quantity selector
Above the Add to Cart button
You can adjust the placement at any time.
Click Save in the top right corner.
Infinite Options is now installed on your theme.
You can begin creating Option Sets inside the app.
Adding Additional Pricing?
If you plan to charge for options using Native Bundling or Product Bundles, you may also need to add the Dynamic Bundle Price block so the product price updates when paid options are selected.
You can add it in the same product template by clicking Add block → Dynamic Bundle Price.
