Multiple sets of labels

Here is a sample script to choose between two sets of labels. I don't have time to complete things like adding new sets but that could be done with five text entry fields and an Add button.

Adobe has info about scripting Bridge on their website https://console.adobe.io/servicesandapis

#target bridge
if(BridgeTalk.appName == 'bridge'){
//create menu
var labelSetsCmd = MenuElement.create('command', 'Label Sets Demo...', 'at the end of Tools'); //create new menu command
}

labelSetsCmd.onSelect = function(){
labelSets();
}

function labelSets(){
try{
app.preferences.mylabels = 'Set 1-1,Set 1-2,Set 1-3,Set 1-4,Set 1-5|Set 2-1,Set 2-2,Set 2-3,Set 2-4,Set 2-5';
var Sets = app.preferences.mylabels.split('|');
var currentSelection = 0;
var currentSet = 0;
var lPalette = new Window('palette', 'Label Sets Demo', undefined, {closeButton:true});
lPalette.preferredSize = [200, 160];
lPalette.frameLocation = [100, 100];
var lpnl = lPalette.add('panel', undefined, '');
lpnl.dropdown = lpnl.add('dropdownlist', undefined, '');
for(var i = 0; i < Sets.length; i++){
try{
lpnl.dropdown.add('item', 'Set ' + (i + 1));
}
catch(e){
alert(e + ' ' + e.line);
}
}

lpnl.lBtn = lpnl.add('button', [15, 25, 130, 45], 'Apply');
lpnl.lBtn2 = lpnl.add('button', [15, 70, 130, 90], 'Cancel');
lPalette.show();

lpnl.lBtn.onClick = function(){
currentSelection = lpnl.dropdown.selection.index;
currentSet = Sets[currentSelection].split(',');
app.preferences.Label1 = currentSet[0];
app.preferences.Label2 = currentSet[1];
app.preferences.Label3 = currentSet[2];
app.preferences.Label4 = currentSet[3];
app.preferences.Label5 = currentSet[4];
}
lpnl.lBtn2.onClick = function(){
lPalette.close();
}
}
catch(e){
}
}
