If you're on a paid plan and don't mind getting your hands dirty in the code, then here are a few common advanced customization questions we get for this theme.

How can I make the Add to Cart button redirect to the Cart page?

Head to Customize Design > Advanced > Layout, and add the following code near the bottom under the last </script> tag.

<script>$(document).ready(function() { $('form.add').unbind('submit'); }); </script>

How can I change the number of products loaded on the Home page?

You can change the number of products that load from 20 to any number up to 100. Head to the Customize Design > Advanced > Home section of your admin, click the Home page, then the custom button to see the default HTML. From there you’ll see the following code at the top:

<div class="page home">
  {% paginate products from products.all by 20 %}

Change the number 20 to how many products you’d like to immediately load on the homepage. Keep in mind that the homepage was meant to display 100 products, so if you don’t have 100 products to display there will be space at the bottom of the page–you’d need to customize your CSS to change that, and you can use these resources if you need help.

How can I add a quantity field to the Product page?

Head to the Customize Design > Advanced > Product page. From there you’ll paste the following bit of code just above the closing </form> tag:

{{ product | product_quantity_input }}

Head to Customize Design > Advanced > Layout and find this line of code:

  <h2 class="title">
    <a href="/products" class="{% if page.full_url contains '/products' %}current{% endif %}">

Replace Products with your preferred title - Shop, Artwork, Classes, etc.
