Data binding
Bind a simple collection for primitive type data or bind a model collection of data.
Filtering
The Blazor Dropdown List component has built-in filtering support for when you have a huge amount of data in the list. For the search input box to appear in the drop-down pop-up list, enable the filtering functionality.
Virtualization
Virtualization enhances UI performance for large data sets. When virtualization is turned on, Dropdown List doesn't initially render the entire data source.
UI customization
Each list item, group title, selected value, header, and footer element of the Dropdown List can be customized using a variety of options.
Grouping
To make it easy to choose an item from the dropdown quickly, the pop-up list items are grouped together by category. The Dropdown List supports grouping nested elements based on categories.
