UI widget libraries

Use Justinmind’s UI widgets to create the visual content in your prototypes. Drag and drop them onto the Canvas, and customize and animate them to make realistic and interactive designs.

Justinmind has over 4000 UI widgets to help you create your web and mobile prototypes, including readymade screens, icons and content blocks for iOS and Android app design.


Widgets are organized into widget groups within Widget libraries, such as Lines and Shapes, Forms and Inputs and Navigation widget groups within the Basic Widget library.

Pre-installed widget libraries

By default, the Basic Widget library comes pre-loaded when you create a new prototype, and can be found in the Widget library palette in Justinmind’s editor.

This library consists of the building block widgets that make up the basics of your interface, such as shapes, text boxes and paragraphs, images and callouts.

Depending on the type of prototype you’re creating, other widget libraries may also come pre-loaded (e.g. if you create an Android mobile prototype, the Android Phone Widget library will appear under the Basic Widget library).
You can find a description of all the Basic widgets in our User Guide.

5. From the gear icon on the right of your new library, select “Exit edit content” to start using the widgets in your prototypes.
6. You can also create groups (a way to classify UI widgets) in your custom libraries, by selecting “New group” in the “Edit content” menu. Give this widget group a name and drag and drop the widgets into it.

You can also share and sync custom widget libraries with other users in your account. Learn more about this here.
