How to create DHTMLX-based web applications

Here you can find best practices in working with DHTMLX Suite widgets and explore live demo applications to kickstart your project.

Optimus micro-framework

Optimus acts as a facilitator of web development based on DHTMLX Suite. It helps to assemble and reuse widgets within a web app and ensures communication between widgets and the environment.

Live demo apps

A gallery of live demos provides real-life examples of using DHTMLX widgets in web apps. You can download any demo, view the source code, and try it out in your project. All demos are created with the help of Suite and Optimus.

CSS widget templates

A set of CSS templates is specially designed for various use cases that can be implemented using DHTMLX widgets. You can borrow the CSS code and apply the styles you like in your web app.

Integration with Angular, React, and Vue.js

DHTMLX Suite is compatible with any client-side framework. There are code examples of how to use DHTMLX widgets with Angular, React, and Vue.js available on our GitHub pages.

Integration with any backend technologies

Being a fully client-side library, DHTMLX Suite can be used with any backend. There is an example of integrating DHTMLX Suite widgets with Node.js in our GitHub repository.

Touch support

You can easily create responsive web applications using DHTMLX Suite due to built-in touch support. Check out how UI widgets work on touch devices in the Touch Support guide.

TypeScript support

The Suite library is equipped with built-in type definitions allowing you to write clean code faster. Browse the TypeScript Support guide with code snippets to learn more.


All DHTMLX widgets are created with accessible design in mind. DHTMLX sticks to WAI-ARIA principles. Widgets support keyboard navigation and can be easily adjusted to match high-contrast UI (read the Accessibility support guide).
