Side Cart

What is a Side Cart?

A side cart (also called a drawer cart or slide cart) is a cart that can be viewed and modified by the customer from any page on the site, allowing the user to make changes to their cart without interrupting the purchase journey flow.

Prerequisites

  • Listed Shopify app is installed
  • Shipping Protection has been approved and enabled for the store
  • Existing merchant with warranty offers on the site

Getting Started

You will need to navigate into your Shopify Store's backend to access the liquid files where you will make the changes listed below.

  1. Go to the Shopify Script Editor.
  2. Create a duplicate of your Current Theme :
    We strongly advise working in a separate, non-live copy of your theme, to ensure your changes aren't visible to customer until you are ready to publish them.
    1. Select the theme you'd like to use, then click Actions -> Duplicate
      Under the duplicate of the theme, usually labelled Copy of {live_theme_name} click Actions -> Rename
    2. Replace Copy of with Extend -
    3. Click Actions -> Edit Code

You will want to use this newly Copied theme to integrate the code changes below.


Code Integration

  1. Add this render to the bottom of your 'extend-configuration.liquid' file:

    <!-- Extend -- Load side cart integration script -->
    {% render 'extend-side-cart-integration' %}
    <!-- Extend -- End Extend code -->
    
  2. Create a new file in the snippets folder and name it extend-side-cart-integration.liquid

  3. Add this code to the contents of this new file:

    <script>
      // Run scripts on DOMContentLoaded to avoid affecting site load time
      window.addEventListener('DOMContentLoaded', function () {
    
        // Only run ajax integration if Extend and ExtendShopify is defined, and the currency is set to USD
        if (window.Extend && window.ExtendShopify && window.Shopify && window.Shopify.currency && window.Shopify.currency.active === 'USD') {

  4. In the section between lines 21 - 33, insert the 5 necessary CSS selectors to complete this integration. Those selectors are for the following:

    1. shippingOfferLocation - Location where the shipping offer will be inserted
    2. cartToggle - Element that must be clicked to open the side cart
    3. quantityUp (If applicable) - Button on each product to increase its quantity
    4. quantityDown (If applicable) - Button on each product to decrease its quantity
    5. removeButton (If applicable) - Button on each product to remove it from the cart

šŸ“˜

Please use this guide on how to get an CSS selector if additional context is needed.

You should not modify any code outside of lines 21 - 38

Below are some general appearance examples for these locations. Keep in mind that they may differ in appearance, and some side carts may not even feature product removal and quantity change options. In these cases, simply ignore the lines requesting those selectors.



Troubleshooting

There is a troubleshooting tool built into the snippet.

To use it simply change the word false to true on line 38.

Remember to change this back to false before publishing the theme!

The tool will display information about which Elements are being grabbed with the CSS Selectors you have added.
