Angular ComboBox | Editable Dropdown | Syncfusion

Overview

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.

Angular Combo Box data binding from different data sources

Data binding

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.

Custom value

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 filter search can be customized to be case sensitive, and can be performed with the 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.

Autofill

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.

Cascading combo boxes
