Populate Textarea in Unbounce Landing Page

Unbounce is a great tool for creating landing pages. One of the reasons it’s so great is because of the easy-to-use landing page builder with simple drag and drop functions. However, when it comes to doing things that are a little more complex, Unbounces page builders limits start to show.

For example, the other day, we wanted to populate a textarea within a form with some default text, so that users don’t have to fill in so many form fields.

Unfortunately Unbounce’s page builder didn’t allow us to populate a textarea with default text, even though you can add default placeholders in the text and email fields of a form.

Luckily, you can add Javascript to an Unbounce page, and this is what helped us to populate our textarea with default text.
