I'm trying to create a form using the FormToolkit that contains a series
of SectionParts. Each section contains input fields pertaining to an
order. The users are used to our old software which saved the data from
each field to the database whenever they navigated from section to
section on the form, or when they were idle for a set period of time. I
need to replicate this functionality, and I'm looking for a way to
visually and passively indicate to the user that a section's contents
are in the process of being sent and saved to the database. I remember
seeing a section that displayed a little waiting widget, but I don't
remember how it was invoked. Does anyone know what I'm referring to?
