Progressive disclosure
Show only what's needed now; reveal further complexity on demand – rather than presenting everything at once.
The pattern behind every “advanced options” fold, every settings page that starts simple, and every form that asks its questions one at a time instead of all at once. The bet it makes: most people need the simple path most of the time, and the ones who need depth will ask for it – so the interface starts quiet and reveals complexity only when requested.
UP bank’s identity-verification flow is the load-bearing version: Australian banking regulation forces a long list of mandatory questions, and UP turns that wall of fields into a contextual sequence – each question shaped by the answers already given – so a compliance form feels like a conversation rather than an interrogation. Done well, the pattern isn’t hiding things; it’s sequencing them.
A note on where you’re standing: the way you most likely arrived at this page – hovering a marked term for a small definition, then clicking through for the full story – is progressive disclosure. The glossary popover shows the one-liner first and holds the detail back until you ask. This page describes the pattern; the mechanism that brought you here demonstrates it.
