Set Field Importance To Drive FastTab Progressive Disclosure

Contributions welcome — open a PR to refine or extend this article.

Description

A FastTab field's Importance property controls whether the field is visible immediately, hidden behind "Show more", or surfaced on the collapsed FastTab header summary line. The three values are Standard (the default, shown in the expanded FastTab), Promoted (also rendered on the FastTab header when the tab is collapsed), and Additional (hidden until the user clicks "Show more"). Misusing these values either clutters the summary line or buries fields users need on every transaction, so reviewers should treat Importance as a deliberate layout decision rather than an afterthought.

Best Practice

Promote only the two to four identifying fields per FastTab that users must read at a glance without expanding — name, status, key amount — so the collapsed header summary line stays scannable. Leave the everyday working fields at Standard, and push rarely-touched fields (legacy compatibility fields, system timestamps, seldom-changed configuration) to Additional. Note that field-level Importance = Promoted is unrelated to action promotion on the page action bar; it governs FastTab field visibility only. Do not rely on initial expand or collapse state, which you cannot set programmatically and which the platform may personalize per user — design assuming any FastTab may be collapsed.

Anti Pattern

Setting Importance = Promoted on most fields of a FastTab so "everything is important" defeats progressive disclosure: the collapsed summary line overflows and conveys nothing at a glance. The opposite failure is marking frequently edited fields Additional, forcing users to click "Show more" on every record. A detectable signal is a FastTab whose fields are nearly all Promoted, or a FastTab containing only Additional fields, which renders as an empty tab until expanded.
