You can define the menuData property as shown here:
You can add/remove the custom menu options by using the spread.contextMenu.menuData property:
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {sheetCount: 2});
initSpread(spread);
};
function initSpread(spread) {
initEvents(spread);
}
function initEvents(spread) {
document.getElementById('addFormatCells').onchange = function () {
var commandRemoved = false;
spread.contextMenu.menuData.forEach(function (item, index) {
if (item && item.name === "markWithRedBg") {
spread.contextMenu.menuData.splice(index, 1);
commandRemoved = true;
}
});
if (commandRemoved) {
return;
}
var commandManager = spread.commandManager();
var markWithRedBg = {
text: "Format Cells",
name: "markWithRedBg",
command: "markWithRedBg",
workArea: "viewport"
};
spread.contextMenu.menuData.push(markWithRedBg);
var markWithRedBgCommand = {
canUndo: false,
execute: function () {
var style = new GC.Spread.Sheets.Style();
style.name = 'style1';
style.backColor = 'red';
var sheet = spread.getActiveSheet();
sheet.suspendPaint();
var selections = sheet.getSelections();
var selectionIndex = 0, selectionCount = selections.length;
for (; selectionIndex < selectionCount; selectionIndex++) {
var selection = selections[selectionIndex];
for (var i = selection.row; i < (selection.row + selection.rowCount); i++) {
for (var j = selection.col; j < (selection.col + selection.colCount); j++) {
sheet.setStyle(i, j, style, GC.Spread.Sheets.SheetArea.viewport);
}
}
}
sheet.resumePaint();
}
};
commandManager.register("markWithRedBg", markWithRedBgCommand, null, false, false, false, false);
};
document.getElementById('addOpenDialog').onchange = function () {
var commandRemoved = false;
spread.contextMenu.menuData.forEach(function (item, index) {
if (item && item.name === "openDialog") {
spread.contextMenu.menuData.splice(index, 1);
commandRemoved = true;
}
});
if (commandRemoved) {
return;
}
var openDialog = {
text: "Open Dialog",
name: "openDialog",
command: showLoginDialog,
workArea: "viewport"
};
spread.contextMenu.menuData.push(openDialog);
};
}
function showLoginDialog() {
if (document.getElementsByClassName('loginBox').length === 0) {

};
}
var loginBoxEle = document.getElementsByClassName('loginBox')[0];
