Extensions: Template custom features in Optimizely X

  • 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 help you make changes in the Visual Editor. Use them to add custom features to your experiences, without ongoing support from a developer.

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 carousal 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.

Other extensions you might build include:

  • banners
  • carousels
  • notification bars
  • lightboxes
  • popup modals

... and more.
