JScript popup dialog with dropdown

I know this can be done in lua, but in jscript? I haven't found anything as yet, if anyone knows of a way to create a dialog with a dropdown list, and then return the value selected to the function, I would love to hear it...

Thanks in advance

I think it is no way to create a dialog with a dropdown list, you can try another way, like popup one list to select. good luck.
