Estimated Reading Time:  12 minutes


The Dropdown component enables your end-user End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. to select a single option from a list. Use the Dropdown component in situations where lists contain too many options for Radio Buttons and Checkboxes components. For example, use a Dropdown component if you have six or more options, or you don't want the full list of options to display on the page at all times.

By default, the Dropdown component stays collapsed until the end-user clicks to open it. After making a selection, the Dropdown list closes again. Your end-user has the option to type the first few letters of their response to quickly find that option in the list.

The Dropdown component is located in the Primary Fields group to the left of the Module Builder.
