DxToolbar.AdaptivityAutoHideRootItems Property

Specifies whether the Toolbar hides root-level items when the browser’s width changes.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

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

Property Value

Type	Default	Description
Boolean	true	true to hide the Toolbar root-level items when the browser’s width changes; otherwise, false.

Remarks

The Toolbar component supports adaptive mode. The following properties specify how the toolbar responds when the container’s width changes:

• AdaptivityAutoCollapseItemsToIcons - If true, the text of all items that contain icons is hidden.
• AdaptivityAutoHideRootItems - If true, the toolbar moves root items one by one to the root submenu until the root level reaches the minimum allowed number of items (specified by the AdaptivityMinRootItemCount property). You can also use the AdaptivePriority and AdaptiveText properties to hide an individual item before other items and specify alternative item text for adaptive mode.
