Examples of Custom Element Extensions for Kentico Kontent

Gallery Stack Overflow

This repository contains samples of the HTML web pages that can be used as Custom Element Extensions in Kentico Kontent.

Custom elements help you with extending the basic functionality of Kentico Kontent UI and thus improving the content editing experience. Custom element is essentially a small HTML application that exists in a sandboxed <iframe> and interacts with the Kentico Kontent app via the Custom Elements API.

Note that Custom elements are only supported in the latest versions of our SDKs.

Custom elements’ samples overview

All of the samples are listed in the Custom Element Gallery. The source code it stored in the /gallery-src folder.

:warning: Disclaimer
Custom elements in this repository should be used for demonstration purposes only.

If you wish to use them in a production project, you should perform a code review and fork/deploy the source code on your own as the custom elements in this repository are subject to change.

NOTE: Some of the custom elements may require further configuration such as custom API keys or be subject to CORS limitation. In those cases please fork the source code repository and adjust the configuration in your repository according to instructions in the element’s README file.

How to create a custom element

You can find a detailed tutorial on how to create a Custom element in our documentation.

Custom element DevKit

To make development of custom elements as easy as possible, we created a custom element devkit. The devkit includes Kentico Kontent alike wireframe and mocked API to enable seamless debugging experience. It is also capable of minimizing all assets and preparing custom element for production use.

Styling your custom elements

By including Kentico Kontent default styles, you can make your Custom element look consistent with the rest of the UI.

The /shared folder in this GitHub repository contains:

We recommend you clone the files and host them locally yourself. The kentico-icons-v1.6.0.woff file needs to be hosted in the same directory as the CSS stylesheet to be properly linked.
