Templates in Blazor MultiColumn ComboBox

14 Aug 20261 minute to read

The Blazor MultiColumn ComboBox supports templating options to customize specific UI elements without altering core behavior. Templates enable adding custom content and layout to improve clarity, branding, or usability.

Header Template

The header is rendered at the top of the popup list and remains static while items are scrolled. Use the HeaderTemplate property to render custom content (such as titles, icons, or additional context) in the header area. For more information and examples, see the header template documentation.
