Remove loading delays (Lazy Loading & Late-Loading Options)

This guide explains when and why you may need to add Infinite Options’ faster loading script, and how to apply it to your Shopify theme.

Fix Late-Loading Infinite Options

If your Infinite Options appear a few moments after the rest of the product page, your theme may be loading Infinite Options later than other scripts.

Installing the Faster Loading Script allows Infinite Options to load earlier, helping your options appear as soon as the page loads.

This issue is sometimes referred to as lazy loading because the options appear after the rest of the page has already loaded.

Is this the right fix?

This guide is for stores where Infinite Options loads after the rest of the product page.

You may notice:

Options appear a moment after the page loads.
The Add to Cart button appears before the options.
The page shifts when the options appear.
Options load inconsistently when refreshing the page.
Options load later on mobile than on desktop.

If your options already load immediately and consistently, you don’t need this change.

Quick Fix

If you’re comfortable editing your theme code, you can install the Faster Loading Script in just a few minutes.

From your Shopify admin, go to Online Store → Themes.
Click ••• → Edit code on your active theme.
Open Layout → theme.liquid.
Paste the following script immediately below the opening <head> tag.

<script src="//d1liekpayvooaz.cloudfront.net/apps/customizery/customizery.js?shop={{shop.permanent_domain}}"></script>

Step-by-Step Guide

Step 1: Open your theme

From your Shopify admin:

Go to Online Store → Themes
Click ••• → Edit code on your active theme.

Step 2: Open`theme.liquid`

In the code editor:

Expand the Layout folder.
Open theme.liquid.

Step 3: Add the Faster Loading Script

Locate the opening <head> tag.

Paste the following script immediately below it.

<script src="//d1liekpayvooaz.cloudfront.net/apps/customizery/customizery.js?shop={{shop.permanent_domain}}"></script>

If Shopify displays a warning such as “Avoid parser blocking scripts,” you can safely ignore it.

Step 4: Save your changes

Click Save.

Why does this fix work?

Shopify themes don’t all load apps in the same order.

On some stores, other apps and theme scripts load before Infinite Options, causing your options to appear later than the rest of the product page.

The Faster Loading Script moves Infinite Options earlier in the page’s loading order, helping it load before most other third-party apps.

It doesn’t change:

Your option logic
Pricing
Conditional logic
Bundling behavior

It only changes when Infinite Options loads.

Confirm the Fix

After saving your changes:

Refresh a product page that uses Infinite Options.
Confirm the options appear immediately.
Verify the page layout no longer shifts while loading.

If the delay is gone, you’re all set.

Is this required for every store
