The Blazor Dropdown List is a quick replacement of the HTML select tags. It has a rich appearance and allows users to select a single value that is non-editable from a list of predefined values. It has several out-of-the-box features, such as data binding, filtering, grouping, UI customization, accessibility, and preselected values.

Filtering and searching drop-down lists

The Blazor Dropdown List Component has built-in filtering support with a rich set of filtering configurations available to match all your application needs. Enable the filtering functionality to show the search input box in the drop-down pop-up list.
