Blazor Mention is an autocomplete-like component for tagging or selecting a user or group from a suggestion list. The component opens a suggestion list when a user starts typing with the ‘@’ character, just like on popular social media sites such as Facebook, Twitter, and more. It supports several out-of-the-box features: data binding, grouping, UI customization, accessibility, and more.

Blazor Mention overview

Data binding

The Blazor Mention component seamlessly works with local and remote data sources such as an array of primitive data, data sets of complex items, JSON data collections, and remote data sources.
