# Conditional Visibility Filter

Set conditional visibility to choose when a tab or widget will appear based on data or a user. This allows you to hide information until it is necessary to show it or to choose who should see specific information when appropriate. 

For example, set a banner telling a user that information is missing when a specific field is empty. 

1. In **Edit layout** click **Set conditional visibility**
2. Select the field. In this example, it will be the "City" field
3. Select operator "is empty"
