Dropdown

{
"default" : "option1",
"options" : {
"option1": "Option 1 Text",
"option2": "Option 2 Text"
}
}

When specifying that an input type should be a dropdown you will need to specify the values of that dropdown. In the JSON above you can specify the default value of the dropdown if it does not have a value. Additionally, in the options object you will specify the value of the option on the left and the text to be displayed on the right.
