Learning > ui > framework > Nested Frontstage Edit this page Nested Frontstages A NestedFrontstage is accessed from a primary Frontstage. It may use all zones and panels, but instead of the App button, the Tool Widget contains a Back button to return to the primary Frontstage. Definition of Nested Frontstage The definition of a nested frontstage is no different from a primary frontstage with one exception: the appButton prop of the ToolWidget component specifies {NestedFrontstage.backToPreviousFrontstageCommand}, which will return to the previous frontstage when clicked/pressed. <ToolWidget appButton={NestedFrontstage.backToPreviousFrontstageCommand} horizontalToolbar={this._horizontalToolbar} verticalToolbar={this._verticalToolbar} /> Code to Open Nested Frontstage The following code that instantiates a nested frontstage, initializes the FrontstageDef, and calls FrontstageManager.openNestedFrontstage to open the nested frontstage. const frontstageProvider = new NestedFrontstage(); const frontstageDef = frontstageProvider.initializeDef(); await FrontstageManager.openNestedFrontstage(frontstageDef); Last Updated: 12 June, 2024
