Describe the Bug

Setting disabled on <FormFieldGroup> applies disabled styling/ARIA to the group, but does not disable the child inputs. The nested TextInput/TextArea remain focusable and editable.

This seems to match the behaviour discussed in #117, which was closed without a linked fix, hence opening a new issue with a minimal repro on current versions.

Steps To Reproduce

1. Render a FormFieldGroup with disabled set.
2. Place a TextInput and TextArea inside FormField children.
3. Try focusing/typing in the inputs — they are still interactive.

Expected Behavior

Either:

• FormFieldGroup disables known child inputs (propagates a disabled context), or
• Documentation clearly states that disabled is visual/ARIA-only and points to supported patterns (interaction="disabled"/disabled={true} per input, or wrapping with <fieldset disabled>).

Additional Information

Current Workaround(s):

Set interaction="disabled" and disabled="true" on each each TextInput/TextArearespectively, or: Wrap the group with a native

` so all real controls inside are disabled.

Products Affected:

Web applications using InstUI FormFieldGroup with group-level disabled expected to disable its children.

Requested Priority:

Normal

Start with the FormFieldGroup, FormField, TextInput, and TextArea implementations and reproduce the behavior in the linked CodeSandbox. Determine whether the supported fix is child-input propagation or documentation of the current behavior and workarounds; done means the chosen behavior is verified for nested controls.
