Specifies whether the vertical scroll bar appears in the drop-down window if its content exceeds the window’s boundaries.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v22.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(true)]
[Parameter]
public bool Scrollable { get; set; }

Property Value

Type	Default	Description
Boolean	true	true if the scroll bar can appear in the drop-down window; otherwise, false.

Remarks

The drop-down window’s height changes to fit its content. When the height is restricted and the content exceeds the window’s boundaries, the control displays a vertical scroll bar. You can set the Scrollable property to false to prevent display of the scroll bar.
