Progress Telerik UI for Blazor
The Blazor Combobox shows a list of options the user can select from. They can easily filter that list to find data faster, or even input their own text. You can customize the appearance of the items and the selection through templates, implement your own custom filtering and load data on demand, react to events, validate the user input and benefit from built-in support for web accessibility standards and keyboard navigation. The ComboBox component works in both WebAssembly (WASM) and Server-side Blazor apps.
You can provide the simplest of data like a collection of numbers or strings, or entire models from your app – the Telerik ComboBox can handle all of them.

Semantic HTML and support for the accessibility standards (including WCAG, Section 508 and WAI-ARIA attributes for screen readers) let users with disabilities use the Telerik combo box with ease. The built-in keyboard support lets you navigate the component and select the desired item without having to touch a pointing device.
The Telerik Blazor ComboBox has several built-in themes such as Default (our own styling), Material (based on the Material Design guidelines) and Bootstrap (which looks like the Bootstrap styling to integrate better). You can easily customize any of out-of-the-box themes with a few lines of CSS, or create a new theme to match your colors and branding by using the Telerik SASS ThemeBuilder application.
