Dynamic Stamp with dropdown

Hi,
Here is an example for a stamp with a dropdown and  a quick script:

var theItems=["item #1","item #2","item #3","item #4","item #5"];
var theField="- Select an Item -";
var theList="var theList \= \{\""+theField+"\": "+(theItems.length+1)+",";
for (var i=0; i<theItems.length; i++) {
	var itemName=theItems[i];
	theList+="\""+itemName+"\": "+(-1*(i+1)).toString()+",";
}
var theList=theList.substring(0,theList.length-1);
theList+="\}";
eval(theList);
var dialogBox={
	initialize: function(dialogBox) {
		this.loadDefaults(dialogBox);
	},
	loadDefaults: function(dialogBox) {
		dialogBox.load({
			LCha: theList,
		})
	},
	validate: function(dialogBox) {
		var oRslt=dialogBox.store();
		var elements=dialogBox.store()["LCha"];
		var testOK=true;
		for (var i in elements) {
			if (elements[i]>0) {
				listValue=theList[i];
				listName=i;
			}
		}
		if (listValue>0) var testOK=false;
		if (!testOK) app.alert("Please select an item",3);
		return testOK;
	},
	description: {
		name: "Stamp with Dropdown",
		elements: [
			{
				type: "view",
				elements: [
					{
						type: "view",
						alignment: "align_fill",
						elements: [
							{
								type: "static_text",
								name: "Items",
								font: "dialog",
								bold: true,
							},
							{
								type: "popup",
								item_id: "LCha",
								width: 150,
								alignment: "align_fill",
							},
						]
					},
					{
						type: "gap",
						height: 5
					},
					{
						type: "ok_cancel",
					},
				]
			},
		]
	}
};
if (event.source.forReal && event.source.stampName=="#bebarth") {
	if("ok"==app.execDialog(dialogBox)){
		event.value=listName;
	}
}
