What are the new components?

The newer version brings two new components such as ColorPicker and Organization chart components.

ColorPicker: ColorPicker is an input component to select a color in different formats (use type property with “hex”, “rgb” and “hsb” values). You can also define the component either in inline or overlay mode.

The inline mode of color picker would appear as below,

You can also define color picker in overlay mode, different formats along with interactive change event callback.

OrganizationChart: OrganizationChart visualized as hierarchical organization data. Even though it sounds like a part of charts section, it will be considered as data component due to it’s data model nature. This component brings  expand/collapse state, selection and customization through templating features.

We can create the powerful organization chart for any kind of organization

The component class need to define TreeNode API data model just similar to Tree,TreeTable components

What are the new features?

The components such as PickList, OrderList, Fileupload, Menus, form inputs and many other miscellaneous components added a big list of new features to 4.1 release.  There are few more components improved with responsiveness, collision detection and accessibility features.

For example, PickList and OrderList components brings the multi filter and drag & drop support across the source and target lists.

The filter feature is enabled by filterBy property and also enables multi field filtering by comma separated values.
