Struct OverlaySpec 

pub struct OverlaySpec {
    pub content: Element,
    pub anchor: Anchor,
    pub modal: bool,
    pub dismiss: Option<ActionId>,
}

A floating layer drawn above the main tree — a menu, popover, tooltip, or dialog. Declared during a build via Cx::overlay; the app lays it out at its Anchor and paints it last (topmost). Its content’s handlers register through the same Cx, so taps/keys inside it work normally.

Fields

content: Element

anchor: Anchor

modal: bool

When true, a translucent scrim is painted behind the overlay and blocks pointer events from reaching the main tree (a modal dialog).

dismiss: Option<ActionId>

Action fired when the scrim (modal) or the area outside the overlay (non-modal) is pressed — typically a dismiss handler.
