Is the Form Application currently editable?
Return the CSS application ID which uniquely references this UI element
Return the active application element, if it currently exists in the DOM

Return a flag for whether the Application instance is currently rendered
An Application window should define its own title definition logic which may be dynamic depending on its data
Assign the default options which are supported by the document edit sheet. In addition to the default options object supported by the parent Application class, the Form Application supports the following additional keys and values:
The default options for this FormApplication class
An application should define the data object used to render its template. This function may either return an Object directly, or a Promise which resolves to an Object If undefined, the default implementation will return an empty object allowing only for rendering of static HTML
An asynchronous inner function which handles the rendering of the Application
Render and display the application even if it is not currently displayed.
Additional options which update the current values of the Application#options object
A Promise that resolves to the Application once rendering is complete
Render the inner application content
The data used to render the inner template
A promise resolving to the constructed jQuery object
Activate required listeners which must be enabled on every Application. These are internal interactions which should not be overridden by downstream subclasses.
After rendering, activate event listeners which provide interactivity for the Application. This is where user-defined Application subclasses should attach their event-handling logic.

Render the Application by evaluating it's HTML template against the object of data provided by the getData method If the Application is rendered as a pop-out window, wrap the contained HTML in an outer frame with window controls

Maximize the pop-out window, expanding it to its original size Take no action for applications which are not of the pop-out variety or are already maximized
A Promise which resolves once the maximization action has completed

Get an object of update data used to update the form's target object
Additional data that should be merged with the form data
The prepared update data
Handle changes to an input element, submitting the form if options.submitOnChange is true. Do not preventDefault in this handler as other interactions on the form may also be occurring.
