Key Features

115+ High-Performance Configurable UI Components

Ext JS delivers the industry’s most comprehensive collection of feature-rich, configurable UI components – including calendar, grids, pivot grid, trees, charts, lists, forms, menus, toolbars, panels, windows, and much more.

Visualisation and Analysis of Complex Data Sets

Ext JS delivers numerous capabilities to help organisations visualise and analyse complex data sets including:

  • D3 Adapter enables developers to add sophisticated D3 visualisations including heatmaps, treemaps, and sunbursts to their applications.
  • Advanced Charting Package lets developers visualise data with a broad range of chart types. The charts use surfaces and sprites developed with a drawing package implemented using SVG, VML, and Canvas to handle browser variations.
  • Pivot Grid enables developers to quickly and easily add powerful analytics functionality to Ext JS applications – allowing users to summarise and analyse data to make more informed decisions.
  • Grid enables organisations to handle millions of records and provides out-of-the-box functionality such as sorting, grouping, column locking, and summary rows.
  • Exporter enables users to export data from the standard grid or Pivot Grid to a wide variety of common formats for additional analysis and information sharing.

Back-end Agnostic Data Package

A robust data package decouples the UI components from the data layer. The data package is protocol agnostic, and can access data from any back-end source.

Layout Manager and Responsive Configurations

A flexible layout manager helps to organise the display of data and content across multiple browsers, devices, and screen sizes. It helps developers to control the display of components, even for the most complex user interfaces.

Customisable Themes

Ext JS components are available in multiple built-in themes, such as Material, that are consistent across platforms. Themes can be easily customised to reflect a specific brand identity.

Accessibility Package (ARIA) for Section 508 Compliance

The ARIA Package lets developers add accessibility support to their applications by providing tools for achieving Section 508 Compliance.
