A GroupElement form element defines a container that holds a set of form elements that can be expanded, collapsed, or displayed together. This is the preferred way to set grouped field configurations within a feature form's or feature layer's formTemplate.

Form with individual field elements	Form with grouped field elements

Nested group elements are not supported.

Example:

const fieldElement1 = new FieldElement({
  fieldName: "inspector",
  label: "Inspector name"
});

const fieldElement2 = new FieldElement({
  fieldName: "inspdate",
  label: "Inspection date",
  description: "Date inspection was handled",
  input: { // autocastable to DateTimePickerInput
    type: "datetime-picker",
      includeTime: true,
      min: 1547678342000,
      max: 1610836742000
    }
});

const fieldElement3 = new FieldElement({
  fieldName: "placename",
  label: "Business name",
  editable: false
});

// Create the group element and pass in elements from above
const groupElement = new GroupElement({
  label: "Business contact information",
  description: "Enter the business contact name",
  elements:[fieldElement1, fieldElement2, fieldElement3]
});

// Next pass in any elements to the FormTemplate
const formTemplate = new FormTemplate({
  title: "Inspector report",
  description: "Enter all relevant information below",
  elements: [groupElement] // Add group element to the template
});

Constructors

new GroupElement(properties)

Parameter:

properties Object optional See the properties for a list of all the properties that may be passed into the constructor.

Property Overview

Property Details

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.

elements FieldElement[]autocast

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

initialState String

Defines if the group should be expanded or collapsed when the form is initially displayed. If not provided, the default value is expanded.

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

Possible Values:"collapsed"|"expanded"

Default Value:expanded

label String inherited

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 an Arcade expression that returns a boolean value. 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 default behavior is that the element is 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 what is 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: "1 == 0"
});

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