OverflowToolbar SAP SE A container control based on {@link sap.m.Toolbar}, that provides overflow when its content does not fit in the visible area. <h3>Overview</h3> The content of the <code>OverflowToolbar</code> moves into the overflow area from right to left when the available space is not enough in the visible area of the container. It can be accessed by the user through the overflow button that opens it in a popover. <b>Note:</b> It is recommended that you use <code>OverflowToolbar</code> over {@link sap.m.Toolbar}, unless you want to avoid overflow in favor of shrinking. <h3>Usage</h3> Different behavior and priorities can be set for each control inside the <code>OverflowToolbar</code>, such as certain controls to appear only in the overflow area or to never move there. For more information, see {@link sap.m.OverflowToolbarLayoutData} and {@link sap.m.OverflowToolbarPriority}. <h3>Overflow Behavior</h3> By default, only the following controls can move to the overflow area: <ul><li>{@link sap.m.Button}</li> <li>{@link sap.m.CheckBox}</li> <li>{@link sap.m.ComboBox}</li> <li>{@link sap.m.DatePicker}</li> <li>{@link sap.m.DateTimeInput}</li> <li>{@link sap.m.DateTimePicker}</li> <li>{@link sap.m.GenericTag}</li> <li>{@link sap.m.Input}</li> <li>{@link sap.m.Label}</li> <li>{@link sap.m.MenuButton}</li> <li>{@link sap.m.OverflowToolbarButton}</li> <li>{@link sap.m.OverflowToolbarToggleButton}</li> <li>{@link sap.m.SearchField}</li> <li>{@link sap.m.SegmentedButton}</li> <li>{@link sap.m.Select}</li> <li>{@link sap.m.TimePicker}</li> <li>{@link sap.m.ToggleButton}</li> <li>{@link sap.m.ToolbarSeparator}</li> <li>{@link sap.ui.comp.smartfield.SmartField}</li> <li>{@link sap.ui.comp.smartfield.SmartLabel}</li></ul> Additionally, any control that implements the {@link sap.m.IOverflowToolbarContent} interface may define its behavior (most importantly overflow behavior) when placed inside <code>OverflowToolbar</code>. <b>Note:</b> The <code>OverflowToolbar</code> is an adaptive container that checks the available width and hides the part of its content that doesn't fit. It is intended that simple controls, such as {@link sap.m.Button} and {@link sap.m.Label} are used as content. Embedding other adaptive container controls, such as {@link sap.m.Breadcrumbs}, results in competition for the available space - both controls calculate the available space based on the other one's size and both change their width at the same time, leading to incorrectly distributed space. <h3>Responsive behavior</h3> The height of the toolbar changes on desktop, tablet, and smartphones. 1.28 sap.m/Toolbar Defines whether the <code>OverflowToolbar</code> works in async mode. <b>Note:</b> When this property is set to <code>true</code>, the <code>OverflowToolbar</code> makes its layout recalculations asynchronously. This way it is not blocking the thread immediately after re-rendering or resizing.
