Selecting checkbox is not displaying drop-down control



User have configured an user interface to display the drop-down control on selecting the check box. However, drop-down control is not displaying in the section on ticking the checkbox.

Error Messages

Not Applicable.

Steps to Reproduce

1. Create a check box property (example Name) in a section.
2. Create a drop-down property in the same section with visibility and required condition expression set as (Name  = true).

Root Cause

An issue in the custom application code or rules.

Selecting the checkbox will not evaluate the visibility WHEN condition, as the condition evaluation is done on submission of the page.
Note that the, Visibility When condition is also evaluated without requiring the need to press the Submit button, when the client side validation is enabled.

The “Run visibility condition on client” and “Run required condition on client” should be checked appropriately to enable the client side validation.


Select the checkboxes "Run visibility condition on client" and "Run required condition on client" for the drop-down property to resolve the issue.
