How to Add Custom Shopify Sections to Any Theme (For Free)

Most Shopify store eventually run into the same problem: your theme looks good out of the box, but you quickly hit its limits. Want a rotating image banner? A modern grid layout? A custom section your competitors are already using? Unless you’re on a premium theme or hiring a developer, you’re stuck.

That’s exactly why we built Flexi Theme Sections.

Flexi is a professional section library for Shopify. It lets you drop designer-quality sections into any theme such as Dawn, Horizon, or premium third-party themes with just a few clicks. And the best part? You can start for free on the starter plan.

In the video above, we'll show you how to add a super customizable section called the content section to your theme. This section is the perfect next step to push your theme's limits and start customizing with flexibility.

 

Why Flexi Instead of Custom Development?

• Save thousands on development → custom sections typically cost $500–$1,000 each when built by a developer.
• Works with any theme → no need to buy a new theme or switch your setup.
• Fast to install → most sections take less than 5 minutes to add.
• Professional design → sections are built to help conversion, not just look good.

How It Works (in 3 Simple Steps)

1. Install Flexi from the Shopify App Store: It’s free to get started. Once installed, you’ll unlock a library of ready to use sections.
2. Pick a Section: Whether you want a rotating banner, testimonial slider, or custom product grid, Flexi has you covered.
3. Drop It Into Your Theme: No coding required. Just add the section in your Theme Editor and customize it with your own content.

That’s it. Your new section is live instantly.

What’s Included for Free?

When you install Flexi, you’ll instantly get access to a starter plan with free sections, including a content section and app blocks. From there, you can unlock the full Flexi Library for just $35/month which is the cost of a single hour of developer time (for a cheaper developer).

The Future of Shopify Themes

Shopify merchants are shifting away from expensive, custom-coded themes. Instead, they’re building modularly, adding sections and blocks as they need them. Flexi is built for that future.

Whether you’re a store owner, freelancer, or agency, Flexi gives you the freedom to build faster, design better, and save money.
