Initial Expansion State

The initialExpansionState option controls the initial expansion state of the cell in the report. In the below demo, all of the cells in the ReportSheet are set to "Collapsed".

Open the demo in a new window to show the designer and edit the options. You can use the following code to set the initialExpansionState option:
window.onload = async () => { const loadingTip = addLoadingTip(); const { spread, designer } = createSpreadAndDesigner(); const res = await fetch('$DEMOROOT$/en/sample/features/report-sheet/layout-settings/initial-expansion-state/spread.json'); await spread.fromJSON(await res.json()); loadingTip.remove(); if (designer) { designer.refresh(); } } function createSpreadAndDesigner() { const demoHost = document.getElementById('demo-host'); if (window !== top) { return { spread: new GC.Spread.Sheets.Workbook(demoHost, { sheetCount: 1 }), } } else { const designer = new GC.Spread.Sheets.Designer.Designer(demoHost, undefined, undefined, { sheetCount: 1 }); return { designer, spread: designer.getWorkbook(), } } } function addLoadingTip() { const div = document.createElement('div'); div.style.position = 'absolute'; div.style.inset = '0'; div.style.display = 'flex'; div.style.alignItems = 'center'; div.style.justifyContent = 'center'; div.style.background = 'white'; div.style.zIndex = '100'; div.textContent = 'Loading data from server ...'; document.body.appendChild(div); return div; }
