AtlasExpandableSection

A header row that folds its content away, with an optional symbol, subtitle and chevron.

Since 1.4.0

AtlasExpandableSection has a header row with an optional symbol, a title with an optional subtitle, and a chevron. A click, Space, Return or Enter on the header toggles expanded and emits toggled(expanded). The content grows and shrinks over AtlasStyle.duration, and while it is folded nothing in it can take the keyboard focus. Section folds a card and leaves the state to the page; this one keeps its own.

Example

AtlasExpandableSection {
    title: qsTr("Advanced")
    subtitle: qsTr("For experts")
    symbol: Symbols.Settings
    onToggled: expanded => settings.advancedOpen = expanded
    AtlasCheckBox { text: qsTr("Verbose log") }
}
