How to add Popup Builder to a Concrete CMS site

Embed Popup Builder on Concrete CMS

01

Create a Popup Builder extension for Concrete CMS on Common Ninja

First, create a Concrete CMS Popup Builder extension on Common Ninja. On the extensions catalog, find the Popup Builder and enter the Editor.

02

Save the Popup Builder extension

When you're done creating the Popup Builder 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 Popup Builder Embed Code

When you're ready to add the Popup Builder extension to your Concrete CMS site, 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 Concrete CMS site.

04

Paste the code to your Concrete CMS website’s HTML field.

Next, go to your Concrete CMS site 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 Concrete CMS’s editor. Add it to your page, and paste the Popup Builder Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Popup Builder extension on your Concrete CMS site.

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 Popup Builder extension on your Concrete CMS 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 Concrete CMS site’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 Popup Builder extension to your Concrete CMS site. You can do this by putting it straight into your Concrete CMS site's HTML code.

Why Use This Widget

Use the Popup Builder widget when you need flexible, targeted overlays for signups, announcements, or offers and do not want to depend on separate tools. You can design popups that match your brand, choose triggers such as scroll, time, or exit intent, and define which pages or segments see them. This is ideal for collecting emails, promoting campaigns, showing gated content, or delivering important notices. When used thoughtfully, popups can lift conversions significantly while staying respectful of user experience. The builder gives you control to test messages, layouts, and timing so you find the balance that works best for your audience.
