Cascading Dropdown: Select Option When Only One is Present

If you are using the Cascading Dropdown question and one of your menus has only one option you might want to have the survey automatically select it for your respondents. While there isn't a built-in way to achieve this; we have a super-simple, copy-and-paste script that will do this for you.

Check it out in an example survey!

OR

Add a survey with this script to your account!

Setup

1. To set this up add a JavaScript Action to the same page as your Cascading Dropdown question.
2. Copy and paste the below script. Save your JavaScript Action and test it out!

$(function() {
    $('.sg-question-cascading select').change(function() {
        var el = $(this);
        if (el.children().length == 2 && el[0].selectedIndex != 1) {
            el[0].selectedIndex = 1;
            el.trigger('change');
        }
    });
});

Note: If you have multiple Cascading Dropdown questions in your survey with a single option in one of the dropdown menus, you will need to add this script to each page where the a Cascading Dropdown is present.
