KitStack
Vertical stack with named spacing and inset values.

Place children in reading order and set gap and inset with LayoutSpace. Use it to compose sections without repeating spacing dimensions.
It aligns children to the start and preserves their natural height. The parent remains responsible for available width.
Complete example
This complete Slint file is a visual composition used to produce the screenshot above. Internal strings without a label property retain the kit’s default language; system dialogs follow the host platform. Projected state and callbacks requesting a decision need host wiring; the standalone fixture does not supply that controller. Set up the Rust project, then see the typed controller application for working editing, validation and selection.
