Rapid Meets Responsive Design

Delivering a great user experience is a crucial component to any digital initiative. But even expert JavaScript, HTML5 and CSS developers say it’s time consuming to create great, consistent experiences across form factors and mobile platforms.

The Mendix UI Framework addresses this challenge, while remaining standards-based, open and extensible. We put responsive app design in the hands of business users and developers through a fully open source, responsive framework integrated into the Mendix visual development environment. With Mendix, even non-designers can quickly create rich, great looking apps that automatically adapt to all device form factors.


Selecting a theme is the first step when creating a new user interface. The theme defines the overall look and feel of your application. We provide a set of beautiful and contemporary themes that you can easily customize, or you can create your own.


Layouts control how users navigate through your app, with top-bar or side-bar main and sub menus. A set of navigation layouts for each device type (phone, tablet or desktop) comes bundled with every theme.

Page Templates

We provide out-of-the-box templates for a wide range of page types, including Overview, Master-detail, Dashboard, Location and Wizard, to name a few. These templates are available for every type of device. Our UI framework also comes with a fully responsive Layout Grid so that your tables scale appropriately on any device.

Design Elements

You can further design your page by adding additional widgets from the rich set of user interface elements that come with the platform, as well as an ever-expanding set of widgets found in the Mendix App Store. And to add your final touches, widgets can be adjusted quickly to your style, color, size, and alignment preferences.

Open, Extensible and Customizable

The Mendix UI Framework is completely open source and accessible on GitHub. The framework leverages Bootstrap, Sass, Compass and Scout. Contribute to the project or customize the Mendix UI Framework to your needs.
