The ListBox for ASP.NET Core is a helper that displays a list of items. It allows multiple selection of items, reorder and transfer between two listboxes. Drag and drop is fully supported as well.
Check out the Telerik UI for ASP.NET Core ListBox demo
The ListBox has a default single selection. In order to configure multiple selections you just need to add selectable: "multiple" to its settings. The selected items can be also reordered.
You can connect the ListBox with another list-box and transfer items between them by dragging and dropping or through the Toolbar buttons.
The Telerik UI for ASP.NET Core ListBox component is one of the many in the suite with out-of-the-box keyboard navigation support. This allows users to easily navigate through the component.

The Telerik UI for ASP.NET Core ListBox has 20+ built-in themes and swatches. Explore the Default (our own styling), Material (based on the Material Design guidelines), Bootstrap (which looks like the Bootstrap styling to integrate better) and Fluent (based on Microsoft Fluent UI) themes and choose the swatch that best suits your application. You can easily customize any theme with a few lines of CSS or create a new one to match your colors and branding with the Progress SASS ThemeBuilder application.
