How to add Before & After Slider to a OpenCart store

Embed Before & After Slider on OpenCart

01

Create a Before & After Slider extension for OpenCart on Common Ninja

First, create a OpenCart Before & After Slider extension on Common Ninja. On the extensions catalog, find the Before & After Slider and enter the Editor.

02

Save the Before & After Slider extension

When you're done creating the Before & After Slider extension, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Before & After Slider Embed Code

When you're ready to add the Before & After Slider extension to your OpenCart store, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the extension embed code. In the next steps, you will paste this code into your OpenCart store.

04

Paste the code to your OpenCart website’s HTML field.

Next, go to your OpenCart store editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the OpenCart’s editor. Add it to your page, and paste the Before & After Slider Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Before & After Slider extension on your OpenCart store.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Before & After Slider extension on your OpenCart extension. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your OpenCart store’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Before & After Slider extension to your OpenCart store. You can do this by putting it straight into your OpenCart store's HTML code.

Why Use This Widget

Use the Before & After Slider widget when your value is best shown through transformation. It is ideal for design work, renovations, cosmetic results, editing, restoration, and any service where the difference between the starting point and final outcome matters. Visitors can drag the slider and see both states in the same frame, which is far more convincing than two separate images. This interaction keeps attention on your results and answers a common question: what does the change actually look like. By placing these sliders on portfolio pages, landing pages, or case studies, you give prospects a quick, visual proof of impact that words alone cannot provide.
