The MultiColumnComboBox component is part of Telerik UI for Blazor, a professional grade UI library with 110+ native components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.


The MultiColumnComboBox for Blazor is an editor component that lets you choose from a table-structured list of predefined options. In its essence, it is a select element but far richer in terms of functionality. Besides being able to bind the component to a list of predefined values, you can also allow the input of custom values.
In terms of appearance, the MultiColumnComboBox is fully customizable through various options and templates for both the input element itself, as well as the dropdown table, including Header, HeaderCell, Cell, Row, and Footer templates.
Some of the features the MultiColumnComboBox exposes are validation, scroll virtualization, item filtering, and many more.
Individual columns are defined through the MultiColumnComboBoxColumn, nested in a common MultiColumnComboBoxColumns tag. Each column must have its Field parameter populated with the corresponding field from the data source. In addition, you can further customize the appearance of said column through parameters like Title and Width.

This Blazor MultiColumnComboBox Overview example is part of a unique collection of hundreds of Blazor demos, with which you can see all Telerik UI for Blazor components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for Blazor or ThemeBuilder.
