Public attributes and slots
| Attribute | Contract |
|---|---|
label | Visible legend fallback, default Group. The label slot overrides visible fallback text. |
description | Group help fallback, default empty. The help slot overrides this text. |
disabled | Presence disables descendants through the native fieldset; false is still present. Control values are retained. |
aria-label | Overrides the accessible group name without replacing the visible legend. |
aria-labelledby | Explicit external accessible-name references, forwarded to the native fieldset. |
aria-describedby | Explicit external description references; defaults to a stable, per-instance help ID. |
hidden | Native host visibility; hidden=until-found retains browser behavior. |
dir | Inherited ltr or rtl text direction. |
class | Host classes can select inherited theme and token overrides. |
Slots: label names the group visibly, help supplies its description, and the default slot contains controls. Fieldsets are not values or validators; they preserve each control's own name, required state, value and errors. Use native form submission or the existing declarative host-service bridge.
