THIS ARTICLE WILL HELP YOU:
  • Use Extensions, or reusable templates, to easily make changes in the visual editor
  • Enable non-technical users tweak parameters of extensions like image carousels, banners, and lightboxes

Optimizely extensions are reusable templates that developers can use to create custom features for non-technical teams. Extensions streamline experiment creation and reduce code duplication. Teams can use extensions to add custom features to experiences, without ongoing developer support.

Extensions are only available on select plans. Please reach out to your Customer Success Manager to request access.

For example, you might use extensions to build an image carousel style for the homepage and code it to rotate between images. From then on, you'll be able to quickly insert an image carousel on any page and modify the images for a specific campaign without writing more code. With extensions, non-technical users can easily add and edit elements on their webpages that might otherwise require coding. Check out how to add a pop-up modal without code for an example of how extensions work.

When you build an extension for an experiment or project, it will only be included in the snippet if it's actually used in at least one of the experiment's variations. This means that archived, unused and draft-mode extensions are never built into the snippet.

If you want to remove an extension from your snippet, you must disable it from the Extensions menu (Implementation > Extensions).

Other extensions you might build include (but are not limited to):
