// Create the group element and pass in elements from above
const groupElement = new GroupElement({
  label: "Business contact information",

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

description String inherited

The element's description providing the purpose behind it.

An array of field elements to display as grouped. These objects represent an ordered list of form elements.

:: esri-md class="panel trailer-1" Nested group elements are not supported. :::

initialState String

Defines if the group should be expanded or collapsed when the form is initially displayed.

Possible Value Description
collapsed The grouped elements appear collapsed.
expanded The grouped elements appear expanded.

Possible Values:"collapsed"|"expanded"

Default Value:expanded

A string value containing the field alias. This is not to Arcade expressions as the title is used instead.

type String

The type of the element. GroupElement is of type, group.

For GroupElement the type is always "group".

visibilityExpression String inherited

A reference to the name of an Arcade expression defined in the expressionInfos of the FormTemplate. The expression must follow the specification defined by the Form Constraint Profile. Expressions may reference field values using the $feature profile variable and must return either true or false.

When this expression evaluates to true, the element is displayed. When the expression evaluates to false the element is not displayed. If no expression is provided, the element is always displayed. Care must be taken when defining a visibility expression for a non-nullable field i.e. to make sure that such fields either have default values or are made visible to users so that they can provide a value before submitting the form.

The referenced expression must be defined in the form template's expressionInfos. It cannot be set inline within the element object.

Example
// Expression created within ExpressionInfos and is referenced in element
const expression = new ExpressionInfo({
  name: "alwaysHidden",
  expression: "false"
});

// Reference an already-defined visibilityExpression set within the ExpressionInfos
const fieldElement = new FieldElement({
  type: "field",
  fieldName: "inspemail",
  label: "Email address",
  visibilityExpression: "alwaysHidden"
});

formTemplate.expressionInfos = [ expression ];
formTemplate.elements = [ fieldElement ];
