A GroupElement form element defines a container that holds a set of form elements that can be expanded, collapsed, or displayed together. Use this to set grouped field configurations within a FeatureForm or Featurelayer formTemplate.

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
});

Property
description String

The element's description providing the purpose behind it.

elements

Property
elements FieldElement[]autocast

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

Nested group elements are not supported.

initialState

Property
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

label

Inherited
Property
label String
Inherited from Element

A string value containing the field alias. This should not be used for referencing fields in Arcade expressions. Rather, the service fieldName should be referenced.

type

Property
type Stringreadonly

The type of the element.

For GroupElement the type is always "group".

visibilityExpression

Inherited
Property
visibilityExpression String
Inherited from Element

A reference to the name of an Arcade expression defined in the expressionInfos of the FormTemplate.

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 as to make certain the specified field has either 1) a default value, or 2) is made visible to the end user to enter a value before submitting the form.

  • The expression must follow the specification defined in the Form Calculation Profile. This expression references field values within an individual feature or in other layers and must return either a date, number, or string value.
  • The referenced expression must be defined in the form template's expressionInfos. It cannot be set inline within the element object.
  • Field and Group elements must be visible if the field or one of the grouped fields is required.
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 ];

Returns
Type Description
GroupElement A deep clone of the GroupElement instance.
