OptionalactiveThe input can be edited only while this holds; otherwise the form shows it disabled, with its value readable and a reason naming what it depends on. Also inactive while an input the condition reads is hidden or inactive, because a setting nobody can change cannot be what enables another.
OptionalinlineConsecutive inputs sharing this id sit on one row, the first one's label leading it: a length beside its source, a switch beside the value and colour it turns on. A multi-line text input always takes a row of its own.
OptionalvisibleThe input is shown only while this holds; otherwise it leaves the form and the tab order, and any draft in it is kept for when it returns. Also hidden while an input the condition reads is hidden.
How a settings form presents an input. The calculation never reads these: a hidden or inactive input keeps its value, and
calcstill receives it.
