How It Works
When customers enter customizations on a Collection Bundle, those properties are transferred to each individual product at checkout — so fulfillment staff see the instructions on every line item.
Example: Customer enters "John Smith" for embroidery → each bundle item shows "Embroidery: John Smith" in the order.
Adding a Custom Property Input
Add a Custom Liquid block in the same section as your Collection Bundle:
<div style="margin: 20px 0;"> <label for="embroidery" style="display: block; margin-bottom: 8px; font-weight: bold;"> Embroidery Text </label> <input type="text" name="properties[Embroidery]" placeholder="Enter your text here" style="width: 100%; padding: 10px; border: 1px solid #ccc; border-radius: 4px;" ></div>
The input must use name="properties[YourPropertyName]" format.
Multiple Properties
Add multiple inputs with different property names:
<div style="margin: 20px 0;"> <label style="display: block; margin-bottom: 8px; font-weight: bold;">Embroidery Text</label> <input type="text" name="properties[Embroidery]" placeholder="Enter name"></div><div style="margin: 20px 0;"> <label style="display: block; margin-bottom: 8px; font-weight: bold;">Thread Color</label> <select name="properties[Thread Color]"> <option value="Gold">Gold</option> <option value="Silver">Silver</option> <option value="Navy">Navy</option> </select></div>
Where Properties Appear
Cart — On the parent bundle product
Order confirmation — On each individual bundle item
Shopify Admin orders — On each line item for fulfillment
