Floating panel

FloatingPanel::make() fixes its children to a corner of the viewport, so they stay in place as the page scrolls. It suits compact persistent controls — a language or appearance switcher, a support launcher — that should always be reachable without taking a slot in the page flow.

FloatingPanel::make()
    ->placement(FloatingPlacement::BottomEnd)
    ->schema([
        SegmentedControl::make('appearance')
            ->options(['light' => 'Light', 'dark' => 'Dark'])
            ->emits('appearance-changed'),
    ]);

• ->placement(FloatingPlacement::…) sets the corner: BottomEnd (default), BottomStart, TopEnd, or TopStart (see the enums reference).
• ->offset($px) is the distance from the viewport edge — 16 by default.
• ->label('…') labels the panel for assistive tech.
• ->trigger([...]) sets the components rendered as the panel’s trigger.

Info

Because a floating panel is fixed to the viewport rather than the page, its examples here are shown as code — a live preview would escape this box and pin itself to the corner of the docs window.
