MARKLESS_ROW_ELEMENT_HANDLE_UNSUPPORTED
This is not a row-ownable element() handle: a Markless compiler error.
Error from the compiler, while it builds your .tsrx files.
What happened
Markless prints the message, the reason, and a suggestion:
MARKLESS_ROW_ELEMENT_HANDLE_UNSUPPORTED: Cannot bind el={<handleName>} inside <element>. A row host takes a declared element() handle, named directly (el={row}) or as one member off a shared() instance (el={select.optionEls}). markless debugging playbook: run pnpm doctor, or read agent/markless.md in the installed @markless/core package
The keyed row record owns one host slot per authored handle and repeat key. Forwarded props, deeper paths, and nested repeat scopes do not identify one compiler-proven row-owned slot.
Declare the handle with const row = element<HTMLElement[]>() in this component or in the shared() factory the row reads, then bind el={row} - or el={family.row} - directly on the keyed row host.
