UI Properties


  • Unique Name: A Unique Name is used to uniquely identify a control in your App. Every control that is added on the screen gets an auto-generated Unique Name on the basis of the Label name given to the control.

  • Label: The text that is displayed helps the user to understand the type of control it represents.

  • Tooltip: The option to add tooltip text as a hint to the user. It is visible when you switch on the visibility toggle property.

  • Description: The option to provide a description that you can add for your control. It is visible when you switch on the visibility toggle property.

  • External CSS: With this property, one can imply exclusive CSS on controls. You can customize your control with CSS by selecting the correct class or id of the control. You can read more here.

  • Caching: When the caching option is selected and if a LOOKUP formula is applied to this control, the value that the LOOKUP returns will be cached and the user will be able to see this value in the fields even when he accesses the microapp later with no connectivity. This option is required when you want your app to be accessible in offline mode as well and getting the latest data from the sheets is not always critical.

  • Hidden: The hidden option helps to hide control from the user. This helps when you don’t want the user to view the control.

  • Trigger Dependents: When you Disable Trigger Dependents, it helps you to reduce or optimize the unnecessary evaluation of the dependent control’s formula. For a detailed explanation refer to this article here. By default, Trigger dependents are enabled. However, in complex apps by switching it off, you would limit the evaluation in the dependent control and in turn ensure quicker response times.

  • Hide on desktop: This option hides the selected control in the desktop view.

  • Hide on Mobile: This option hides the selected control in the mobile view.

  • Dynamic Height: This option dynamically increases /decreases the height of the text control based on the given content.

  • Maintain space when hidden: This option maintains the specified space between controls when a particular control is hidden. When control is hidden the space is maintained in the preceding control depending on the space the previous control has occupied.
