  • Type : The Type field is automatically generated depending upon the type of control used. In this case, it is a “dhq_dropdown” type.

  • 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.

  • Tooltip: This allows you to add the Tooltip text that would provide a hint to the user for providing input. The Tooltip icon would be visible if you switch on the Show tooltip icon toggle property available below.

  • Description: Is the description that you can add for your controls. The Description would only be visible if you switch on the Show Description toggle property available below.

  • 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.

  • Submit Data : This field lets you determine whether to send the value of the control or not in Workflow based on various control states. There are three conditions that could be set for this field.

    1. Always : When this condition is selected, the selected fields will be submitted irrespective of the state of the Dropdown.

    2. Never : When this condition is selected, the selected fields will never be submitted irrespective of the state of the Dropdown.

    3. No When Hidden : When this condition is selected, the selected fields will be submitted if the Dropdown is visible and not submitted when the Dropdown is hidden .

  • Required : When you select the required option, the field becomes a mandatory field and the user can not submit without filling it.

  • Read Only : When you select this option, the user will no longer be able to edit this field.

  • Hidden : The hidden option helps you to hide the field from the user. This might help if you want to show certain fields only when a specific condition is met/not met.

  • Caching : When the caching option is selected and if a LOOKUP formula is applied to this control, the state that the LOOKUP returns will be cached and the user will be able to see this state in the Dropdown even when the user 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 always is not critical.

  • Hide Label : This option hides the label of the Dropdown from the view.

  • 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 is 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 a control is hidden the space is maintained in the preceeding control depending on the space the previous control has occupied.

  • Border: This option lets you change the color of the border of the Dropdown container.

  • Format: This is the Format of the Dropdown as Tray type or Classic type.
