FastTabs, as shown in the precedingCustomer Card and Sales Order screenshots, are collapsible/expandable replacements for traditional left-to-right forms tabs. FastTabs are often used to segregate data by subject area on a Card page or a Document page. In the preceding screenshot, the General and Lines FastTabs are expanded and the remaining FastTabs are collapsed. Individually, important fields can be promoted so that they display on the FastTab header when the tab is collapsed, allowing the user to see this data with minimal effort. Examples appear on the Sales Order's collapsed Invoice Details and Prepayment FastTabs. Promoted field displays disappear from the FastTab header when the FastTab is expanded.
