The HtmlElement component
This component can display a single HTML element in the form, for example a header or an image.
The HtmlElement does not have a value and therefore it is not part of the submission data.
In addition to the properties and methods listed below, this component inherits properties and methods from the superclass Component. For example, any HtmlElement component has a label and hidden property even though these are not explicitly listed here.
