The React ComboBox component, part of KendoReact, is a form component designed to let end users choose a predefined value from a list, and often is used as a much richer version of the select HTML element. The component naturally highlights the dropdown that the values appear in a dropdown arrow next to the text input, and the component sports a whole slew of features to make picking the proper value as easy as possible.
The built-in filtering mechanism of the KendoReact ComboBox automatically reduces the number of available choices in the ComboBox dropdown. Filtering can be configured in various ways, including "starts with" or "contains" to ensure the most intuitive filtering behavior for any scenario.
With the suggestion feature enabled, the KendoReact ComboBox will attempt to autofill the input element based on the closest available value. This suggestion will continue to update as the user types.
By default, the KendoReact ComboBox renders items with plain text. Certain scenarios call for more advanced rendering and this is where the custom rendering feature of the React ComboBox shines! This allows a custom renderer to be injected for any list item, header or footer element, as well as the suggestion lists when no data is availableâenabling developers to take full control over the look and feel of the ComboBox component.
Depending on your requirements the React ComboBox may be bound to thousands or hundreds of thousands of data items, which can be quite taxing on any modern browser to render. Thanks to the built-in virtualization feature of the KendoReact ComboBox, scrolling through large amounts of data is done with buttery-smooth performance.
Popularized by Material Design, the floating label starts off as a placeholder in an input element only to animate out and float above the input and act as a label. The KendoReact AutoComplete component comes with support for floating labels built-in, no matter what design language you chose to incorporate it with.
The KendoReact ComboBox is most often used as a part of a form to help the user select from a longer list of data. In this vein, the React ComboBox supports being added to any plain form element or integrated into an existing React Form library (including the Form component from KendoReact). Thanks to built-in styling and behavior around validation, this UI component can fit with any form.
Keyboard navigation has become a crucial part of website navigation for several reasons ranging from speed of data input to accessibility concerns. Thankfully, this React ComboBox comes with built-in keyboard navigation to help navigate through every part of the component and assist with selecting a value with ease.
Creating accessible React UI components is a core concept of KendoReact, and the ComboBox is no exception! The KendoReact ComboBox is compliant with Section 508 standards, is AA rated with WCAG 2.0, and follows WAI-ARIA standards.
