Source forms
The forms below are header patterns: square brackets mean optional syntax, | lists alternatives, and words such as selector, value and caption are placeholders. They are source fragments requiring the stated owner, not complete applications. Content suites use ordinary indented Can; named slots use slot name with a nonempty indented suite. Slots cannot mix with regular direct children.
Appearance options are optional and limited to the per-entry values below. No raw classes, arbitrary properties or event handlers are accepted. Input captions derive from their fields. A selector has at most one writable control, and unmentioned eligible inputs still render in owning schema order. A collection/result scope ends field placement unless it contains a new explicit field owner.
avatar
Header: avatar image [caption=text] [fallback=text]. Leaf. The image must be authorized; caption and fallback are safe text.
Appearance: variant=solid.
carousel
Header: carousel [sequence]. Requires item slots. With a query or typed readable sequence, exactly one slot item template renders for each admitted row; without an operand, repeated authored slot item suites are explicit items. Scope, field grants and stable ordering remain checked.
Slots: slot item (required, repeatable).
Appearance: variant=solid, orientation=horizontal|vertical.
hover_gallery
Header: hover_gallery [sequence]. Requires item slots. With a query or typed readable sequence, exactly one slot item template renders for each admitted row; without an operand, repeated authored slot item suites are explicit items. Scope, field grants and stable ordering remain checked. At most ten authorized images; keyboard/touch alternatives remain available.
Slots: slot item (required, repeatable).
list
Header: list query [columns=fields]. Collection leaf using default row presentation, or a nonempty row presentation suite. Optional order, search, filter, empty, defaults and display=split retain the canonical collection semantics.
pagination
Header: pagination. Leaf only within a collection; it uses that collection’s cursor, filter and ordering state.
table
Header: table query columns=fields. Collection leaf using default row presentation, or a nonempty row presentation suite. columns= is required. Optional order, search, filter, empty, defaults and display=split retain the canonical collection semantics.
Appearance: size=xs|sm|md|lg|xl, variant=solid.
