The Conditional tab in the Form Designer allows you to place conditions on components in your form, in order to hide or display them.

The Conditional tab has a Simple section.

The Simple section of the Conditional tab allows you to hide or display a component, based on the value of another component.

The Simple section consists of three fields:

  1. This component should Display - from this dropdown list, choose:

    • True if you want to condition when the component displays.
    • False if you want to condition when the component hides.
  2. When the form component - from this dropdown list, choose a component in the form to act as a condition.
  3. Has the value - type in the value that conditions the component when to display or hide.

Check out the tutorial about creating simple conditions from the Form.Activities guide.


The Logic tab of the Form Designer allows you to create conditions and advanced logic scripts that can change the state or the behavior of the selected form component.

Using advanced logic, you can dynamically change the controls, looks, and feel of a form component.

A form logic consists of two parts: the trigger and the action.


The logic trigger is the condition upon which the action takes place. For example, you may want to display a specific form field only when a checkbox option is selected. In this case, the checkbox option is the trigger, and displaying the form field is the action.

There are four types of logic triggers:

Trigger type




You define one triggering form component and value.


You provide a JavaScript logic for a form component or form data.

Use the JavaScript syntax to create complex logic, such as loop or dynamic behavior.

JSON Logic

You provide a JSON logic for a form component or form data.

Recommended in cases where JavaScript is not permitted.

Cannot support loops or dynamic behaviors.


You define a component event, which once emitted by the corresponding component, triggers the desired action.


The logic action is the form component behavior that should happen based on the logic conditions you set (i.e., the trigger). For example, you may want to activate a button for users of a specific age. In this case, the age range is the trigger, and activating the button is the action.

There are four types of logic actions:

Action type




The trigger changes one of the available component properties, such as Tooltip, Description, CSS class, etc.

The available properties depend on the type of the triggering component.


The trigger changes the value of the corresponding component.

The action must be defined using JavaScript syntax.

Merge Component Schema

The trigger changes the component schema parameters found in the component JSON.

To see the schema parameters you can change, hover over the corresponding component and click Edit JSON.

You can change multiple parameters within one action.

Custom Action

You define a custom action using JavaScript syntax, in the same you would define the JavaScript trigger type.



The Templates tab is specific to the Edit Grid component only. The Footer template allows you to customize the grid using JavaScript. You can modify the look of the footer.

Footer Template

This is the Lodash Template used to render the footer of the Edit Grid component.

There are two variables available:

  • value - the array of row data
  • components - the array of components in the grid


The File tab is specific to the File component only. The File tab allows you to customize a File component, through specific settings and properties.

These are the properties available in the File tab

  • Directory - places all the files uploaded in this component, in the directory specified. The string must end with /.
  • Upload Only - allows users only to upload files. The download option will be unavailable, when checked.
  • File Types - allows you to specify the file types, in order to classify the types of files that the user uploads. Recommended when a user uploads multiple types of files and you want the user to specify the type of each file uploaded.
  • File Pattern - allows you to specify file extensions that will be allowed to upload. Other file extensions that are not specified, won't be uploaded.
  • File Minimum Size - sets the minimum size for the uploaded file.
  • File Maximum Size - sets the maximum size for the uploaded file.
