Reference

Per-group reference pages listing every shortcut, its signature, and a link to the widget it renders.

• gui.inputs — every input shortcut.
• gui.actions — every action shortcut.
• gui.displays — every display shortcut.
• gui.layouts — every layout shortcut.
• gui.selectors — every selector method, organized by chain position.

Conceptual walkthrough

If you’re new to the Form Definition API, read the conceptual pages first — the reference is a dictionary, not a tutorial.

• How it works — the user-facing tour of gui.*, signatures, and the building blocks.
• Tags — labelling widgets so the selector layer can target them.
• Custom Widgets — gui.<group>.custom(...) for widgets you’ve implemented yourself.
• States — named conditions plus include / exclude / when for gating widgets.
• Runtime Functions — make any prop reactive by passing a callback instead of a static value.
• Events — onClick, onChange, onLoad, onFilter, onBlur, plus the special submit.
• Selectors — the behavior layer that decorates widgets by type, tag, or uid.
