All fields have a
field and a
label setting. The
field is the name of the field, or property of the schema. This can be free typed or, if a schema exists on the form, selected from a list. There are unique components for every type of data, and if your form has a schema then you'll only be able to choose field names which fit the particular type of component that is selected. The
label setting is the label that will be displayed beside or above your field. Most fields also have a
placeholder setting to control the text displayed when the field is empty.
