The ASP.NET Core DropDownTree component takes the best of the TreeView and the DropDown and represents hierarchical data in a tree-like structure with options to select multiple items and render custom nodes. You can use the built-in features to add images or checkboxes to your DropDownTree items as well as bind to local or remote data.

Save space without losing the context of your form fields with the DropDownTree floating label feature. Ensure a smoother and more efficient end-user experience by adding a label that slides above the input field upon clicking.
The DropDownTree adaptive mode enables a mobile-friendly rendering of its suggestion list popup. Simply set the AdaptiveMode parameter to AdaptiveMode.Auto – this will trigger the picker component to automatically adapt to the current screen size and will change its rendering accordingly.
