DI token a CngxChipInGroup leaf injects to find its parent chip group
CNGX_CHIP_GROUP_HOST
Tokenv0.1.0WCAG AA
InjectionToken<CngxChipGroupHost>
Description#
DI token a CngxChipInGroup leaf injects to find its parent chip
group. Always provided via
{ provide: CNGX_CHIP_GROUP_HOST, useExisting: <Self> } - never
via concrete-class injection. Required (NOT optional) on the leaf
side: a leaf without a parent throws NullInjectorError at
construction (fail-fast - silent dual-source-of-truth would be
worse).
Standalone chips outside any group use [cngxChipInteraction]
instead, which provides CNGX_CONTROL_VALUE directly without ever
touching this token.
