The Angular ComboBox component is a drop-down list with an editable option that also allows users to choose an option from a predefined pop-up list. It can be used as an alternative to the HTML select tag and has several out-of-the-box features such as data binding, filtering, grouping, cascading, templates, UI customization, pop-up list customization, and more.

Angular Combo Box data binding from different data sources

Data binding

You can bind data from a variety of data sources in an array or list of primitive data, JSON data collections, or remote data sources using different kinds of adapters such as OData, OData V4, URL, JSON, and Web API.

The component uses the Essential JS 2 data manager to manage data, and also has customization options for data requests and processing.

Custom value

The editable combo box allows the entry of a custom value when the option the user searched for is not available in the pop-up list. Also, you can set a value for the combo box or get the selected value from the combo box at any time through the interactive APIs.

Built-in filtering support with a rich set of filtering configurations is available to meet all your application needs.

Angular ComboBox filtering search based on custom algorithm

Custom filtering

Filter queries are customizable, and you can use your own filter libraries to filter data.

Angular ComboBox filtering with diacritic symbol sensitivity

Diacritic sensitivity

The Angular ComboBox component supports diacritic character sensitivity. This behavior can be turned on or off.

Angular ComboBox filtering with case sensitivity and minimum search characters

Filter settings

The filter search can be customized with case sensitivity, and can be performed with minimum query string characters.

Angular ComboBox Grouping of pop-up list items based on category

Grouping with category

Group the pop-up list items with a corresponding category that makes it easy for users to pick an item quickly from the drop-down, and also improves the visual experience for users.


The autofill option allows users to easily search through options in the combo box. When a user is typing a query string to search, the available matching options will be filled automatically.

Cascading combo boxes

The Angular ComboBox component provides an option to create multiple cascading combo boxes, which helps users populate data for a child combo box based on the current selected value of the parent combo box.

Another important combo box feature is templates, which allow you to make custom appearances for the header, footer, and list items in the pop-up list.

Styling Angular ComboBox pop-up list with item template

Customizing the UI

You can customize each part of the combo box based on your application requirements.

Angular ComboBox pop-up list with icons

Icons in list items

Each list item can be configured to display a custom icon to improve the component’s readability and appearance.

Angular ComboBox pop-up list custom appearance when no records are found

Empty record

Angular ComboBox the pop-up list dimensions customization

Customize dimensions

The dimensions of the pop-up list can be customized to fit the application.
