Horizon Theme - Missing Collapsible Row Block and Limited Product Page Customization

[ladylantana]

ello,

I’m building a luxury fashion store using the latest Horizon theme.

I’ve spent several days trying to customize my product pages and collection pages without editing the theme code.

After following Shopify Help documentation and Shopify AI guidance, I’m still unable to achieve some very basic customizations.

My questions are:

1. Product Information
   The Horizon theme does not show a “Collapsible Row” block under:

Customize → Products → Default Product → Product Information → Add Block

I would like to create separate accordion sections for:

• Description
• Materials
• Fit
• Care Instructions
• Shipping & Returns

The Shopify documentation suggests using Collapsible Rows, but this block simply does not exist in my Horizon theme.

Is this expected behaviour?
Has this feature been removed?
Is there an official no-code solution?

2. Collection Page

My collection pages display 5 products per row on desktop.

Is there an official way to change this to 4 columns without editing theme code?

3. Product Cards

Is it possible to display product variants or color swatches underneath product cards on collection pages?

4. Policy Pages

Can the layout and typography of Policy pages be customized through the Horizon Theme Editor without custom code?

I would really appreciate clarification from someone familiar with the Horizon theme, as the available documentation seems to describe functionality that is not present in my version.

Thank you very much.

1. The block name is “Accordion”, under Layout;

2. Horizon uses another approach – it sets the desired size of the product card and then fits as many per line as fits.
   This allows for better looks on wide and ultrawide monitors, especially with full-bleed section rather than page-width-limited.
   
   Having said that – you can change this to fixed number of columns with small CSS code, but again, on ultrawide monitor there is a risk of blurry images, etc.
   CSS code (can be used in “Custom CSS” setting, either in section, or in “Theme settings”):

/* fix product grid to 4 columns on desktop */
.product-grid.product-grid--grid {
  --product-grid-columns-desktop: repeat(4, 1fr); 
}

3. Yes, you can add the “Swatches” block to the product card:
   
   
4. Not really. You can reach the policy pages in “theme edit”, but can’t really change much there.
   The reason for this is that, say Shopify uses textual content of your policy pages elsewhere (links from the sign-in/log-in popup, for example), which are hosted separately from your theme.
   
   Of course, nothing prevents you from creating your own custom Pages for policies with better looks.

Hi, Thank you so much. Could you please tell me exactly where I can find the Accordion block in Horizon? Which template and which section should I open?
