The Angular ComboBox component is a drop-down list with editable textbox 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.
Bind data from different data sources in an array or list of primitive data, JSON data collections, or remote data sources using 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.
The editable combobox 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 combobox or get the selected value from the combobox at any time through the interactive APIs.
The Angular ComboBox provides a built-in filtering support with a rich set of filtering configurations to meet all the application needs.
Filter queries are customizable, and users can use their own filter libraries to filter data.
The Angular ComboBox component supports diacritic-sensitive search. This behavior can be turned on and off.
The filter search can be customized to be case sensitive, and can be performed with the minimum query string characters.
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 the options in the combo box. When a user types a query string to search, the available matching options will be filled automatically.
The Angular ComboBox component provides an option to create multiple cascading combo boxes. Users can populate the data source of the second ComboBox based on the value selected from the first ComboBox.
Another important combobox feature is templates, which allow you to make custom changes to the header, footer, and list items in the pop-up list to make them look unique.
Design your own header for the pop-up list using a header template.
Define the appearance of each item in the pop-up list with item templates.
Design your own custom and static footers for the pop-up list using footer templates.
Users can customize each part of the combobox based on their application requirements.
Each list item can be configured to display a custom icon to improve the component’s readability and appearance.
Configure a custom look for the pop-up list when there are no items to display.
The dimensions of the pop-up list can be customized to fit the application.
Since the combo box is a form component, it supports HTML forms, template-driven forms (Angular), and reactive forms.
The Angular ComboBox component supports the built-in themes Material, Bootstrap, Fabric (Office 365), Fluent, Tailwind CSS, and high contrast. Users can customize these built-in themes or create new themes to achieve their desired look and feel by either simply overriding SASS variables or using our Theme Studio application.
The Angular ComboBox component supports a responsive mode that provides an adaptive, redesigned UI appearance for mobile devices.
Fully supports WAI-ARIA accessibility guidelines to work with screen readers and assistive devices.
Follows WAI-ARIA best practices for implementing keyboard interaction.
Designs the UI visual elements such as foreground color, background color, line spacing, text, and images based on WCAG 2.0 standard.
Supports right-to-left (RTL) direction for users working with RTL languages like Hebrew, Arabic, or Persian.
Developers can customize all UI elements and control their behaviors according to the end user’s requirements using its rich set of client-side APIs.
Easily get started with the Angular ComboBox using a few simple lines of HTML and TS code example as demonstrated below. Also explore our Angular ComboBox Example that shows you how to configure the combobox in Angular.
