Taming the Checkout Clutter: Understanding Hidden Line Item Properties in Shopify

Hey fellow store owners! Let's talk about something that's probably caused a few head-scratches in your Shopify journey: those pesky, sometimes confusing, internal line item properties that pop up in your checkout or admin order views. We've all been there, looking at an order summary and wondering why a product seems to be listed twice, or why our admin view is suddenly filled with lines like _cl_options_price:500. It can feel like Shopify is just throwing extra data at you, but as a recent discussion in the community highlighted, there's often more to it than meets the eye.

Liri, a merchant in the community, kicked off a great thread asking about hiding these internal properties, especially from apps like "Live Product Options." They were seeing product duplication in checkout and a really cluttered admin view. It’s a common pain point, so let's break down what's happening and what you can do.

Understanding the 'Why': Apps, Nested Lines, and Shopify's Role

The core of the issue, as Maximus3 and tim_tairli pointed out, often comes down to how certain apps integrate with your store, particularly when they use something called "nested cart lines." Imagine you're selling a customized product, say, a skirt, and you offer an add-on like a "Side Pocket."

Instead of just adding a simple property, some apps, especially those handling product bundles or paid options, might create a structure where the original product itself (the skirt) is treated as a "child" component of the overall customized item. This allows them to bundle the add-on price into the main product's price. Here's a visual example from Maximus3's reply:

When this happens, Shopify isn't actually duplicating your product. Instead, it's faithfully displaying the product structure that the app has created and passed to it. If you don't select the add-on, the duplication often disappears:

This "nested" display, while technically correct from the app's perspective, can be super confusing for customers, as Liri rightly pointed out. It often appears in an expandable section labeled "part of product XY" and shows the entire product again, image and all:

Checkout vs. Admin: Two Different Beasts

It's important to differentiate between where you're seeing these properties, as Lumine and Maximus3 clarified. The rules for the checkout summary are different from the admin order view.

The Checkout Order Summary

This is where customer confusion can really hurt. Ideally, internal properties (like _cl_options, _cl_options_currency, etc., which start with an underscore) are meant to be hidden from customers in the cart and checkout summary. If you're seeing them, or worse, seeing duplicated products because of them, it's likely an issue with how the app is injecting these properties.

Maximus3 laid out how this works in code:

or

Properties starting with an underscore, like _campaign, are specifically designed to be suppressed from checkout rendering. If an app isn't doing this correctly, it's on them.

The Shopify Admin Order View

This is a different story. The admin order page is designed to be a permanent record of everything associated with an order. Every single line item property, whether it's hidden from the customer or not, will show up here. This is by design, and you genuinely can't hide them from this view. It's Shopify's way of ensuring you have the full, immutable context of what was ordered. While it can look cluttered, especially with complex products, it's considered the "source of truth."

This also extends to third-party invoicing tools (like Billbee, as Liri mentioned) that retrieve data via the Shopify API. Since the API pulls all these properties, they'll show up in those tools too, making it hard to filter them out there.

What Can You Do About It?

Given these distinctions, here's an action plan based on the community's insights:

1. For Checkout Duplication/Visibility Issues: Contact Your App Developer

   If you're seeing duplicated products or internal properties (especially those starting with an underscore) in your checkout summary, the first and best step is to reach out to the app's support team. Explain the issue, referencing the fact that properties starting with an underscore are supposed to be hidden from checkout rendering. The app developers are responsible for how they name and inject these properties. They might be able to:

   • Adjust their app's configuration to ensure properties are correctly hidden.
   • Modify the "parent" product title to be more descriptive (e.g., "Customized skirt" instead of just repeating "Women's linen skirt with button placket") to reduce confusion.
   • Potentially change their app's logic to not hide the add-on product at all, giving customers a clearer breakdown of the order and price structure.

2. For Admin View Clutter: Understand and Adapt

   Unfortunately, for the Shopify admin order view, there's no native way to hide these properties without requiring Shopify Plus (which offers more advanced API control, but Liri specifically asked for solutions without it). Your best bet here is to:

   • Educate yourself and your team: Understand that this data is there for a reason – it's the complete record. Train your team to recognize and largely ignore the internal properties when scanning orders.
   • Focus on what you can control: While you can't hide them from the admin UI, you can ensure your customer-facing elements (checkout, order confirmations, shipping labels) are clean.

3. Review Your App Choices

   This situation highlights the importance of choosing apps carefully. When evaluating apps that handle product options, bundles, or customizations, it's worth asking their support team how they manage line item properties and their visibility in both the checkout and admin areas. A well-designed app will minimize customer confusion while still providing necessary data for merchants.

Ultimately, while Shopify ensures line item properties are passed through and attached to your orders, it's the responsibility of the app developers to implement them in a way that's both functional and user-friendly. So, if you're facing this, don't hesitate to engage with your app's support – they're the ones who can truly fine-tune how this data appears to you and your customers.
