5.2.1.1. Single-Select Dropdown Field with Modal Window

Although most single-select fields release a dropdown menu, there are some that instead open a modal window.

*A modal window is a pop-up window that disables the main form, requiring users to interact with it before they can regain access. Users can interact with a modal typically by either completing the set task or exiting the window.

To use a single-select dropdown field linked to a modal window, follow these steps:

1. Click on the icon. It will open a modal window containing the options available to choose from.
2. Navigate through the options and select the desired one by double-clicking on it.
   • Users will then be returned to the main form where they will find the field now populated with their selection.
3. Otherwise, to return to the main form without making a selection, click on the Exit (X) button.
   

In the example below, the modal window contains a tree view control to help users navigate through a hierarchical structure of options.

*Users can determine the contents of the modal window by creating the form and linking the corresponding form behavior to the control.
