How to add Corner Button to a Concrete CMS site

Embed Corner Button on Concrete CMS

01

Create a Corner Button extension for Concrete CMS on Common Ninja

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

02

Save the Corner Button extension

When you're done creating the Corner Button 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 Corner Button Embed Code

When you're ready to add the Corner Button 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 Corner Button Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Corner Button 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 Corner Button 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 Corner Button 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 Corner Button widget when you need a persistent call to action that stays visible without interrupting content. A fixed corner button can highlight promotions, open a form, trigger chat, or guide visitors to a key page no matter where they are on the site. This is useful for long pages, ecommerce stores, and funnels where a single action matters most. Because it does not block reading, visitors feel in control, yet they always have a clear next step in view. With strong labeling and subtle design, the button reduces navigation friction, increases clicks on high value actions, and keeps conversions accessible even for users who scroll deeply before deciding.
