A FormTemplate formats and defines the content of a FeatureForm for a specific Layer or Graphic. A FormTemplate allows the user to access values from feature attributes when a feature in the view is selected.
The FormTemplate can be set directly on a FeatureLayer, a FeatureForm, or its view model. The template consists of various elements that display a specific type of form data.
// Create the Form template and pass in elements
const formTemplate = new FormTemplate({
title: "Inspector report",
description: "Enter all relevant information below",
elements: [groupElement] // Add all elements to the template
});
// Add a new feature form with grouped fields
const form = new FeatureForm({
container: "form",
groupDisplay: "sequential", // only display one group at a time
formTemplate: formTemplate // set it to template created above
});
