# Display Conditions

**Display Conditions** can be used to change the runtime status of [HMI Components ](/hmi-designer/hmi-components.md)while the robot program is running. 

Changing runtime status of HMI elements can be usefull to:

* **Show** or **Hide** HMI components
* **Enable** or **Disable** HMI components

Display Conditions can be expressed as simple **boolean variables** or as more complex **conditional statements**. You can setup Display Conditions for each HMI component inside its properties panel.

Runtime status of HMI components can be changed also programmatically using [HMI Commands.](/hmi-designer/hmi-commands.md)

You can see Display Conditions in action inside the [Machine Tending Example](/hmi-designer/working-examples/universal-robots/machine-tending-example.md).
