Add to New Menu
From MobileX for SageCRM
The menu is the in object
cApp.ddNew
"ddNew" is a cTSDropDown object.
and you call "addItem" on that to add it.
addItem = function (ItemName, Caption)
In a plugin you would use the "onDocumentReady" method and add in the code.
Example below
var onDocumentReady = function () {
var menuitemx = cApp.ddNew.addItem("menuitemname", "menu title");
menuitemx.pr_onclick = "cApp.doSomething();";
}
