MUIRadioGroup

MUIRadioGroup wraps the Material UI RadioGroup for a single choice among options, storing the selected value. Supports primitive or object options via labelKey/valueKey.

Usage#

import MUIRadioGroup, { MUIRadioGroupProps } from '@nish1896/mui-components/mui/radio-group';
const [plan, setPlan] = useState();

<MUIRadioGroup
  fieldName="plan"
  value={plan}
  onValueChange={({ newValue }) => setPlan(newValue)}
  options={['Free', 'Pro', 'Enterprise']}
/>

Example with an array of objects:

<MUIRadioGroup
  fieldName="nationality"
  value={nationality}
  options={[
    { code: 'AUS', country: 'Australia' },
    { code: 'IN', country: 'India' },
    { code: 'USA', country: 'United States of America' }
    { code: 'UAE', country: 'United Arab Emirates' }
  ]}
  labelKey="country"
  valueKey="code"
/>

Props#

For object options, pass labelKey and valueKey. Props marked with * are required.

NameTypeDescription
fieldName*string
Name/path of the field. Used to derive the id, the default label, and the name attribute. This prop is required for all components.
valuestring | number | null
Currently selected option value, normalized with valueKey for object options. undefined/null are treated as no selection.
onValueChange*({ newValue, event }) => void
Called on every selection with the normalized option value and the original change event.
options*string[] | number[] | object[]
An array with string, numeric or object values. Make sure to pass labelKey and valueKey when options is an array of objects.
labelKeystring
Property name used as the visible label for each option. Required when options is an array of objects.
valueKeystring
Property name used to derive the exposed value for each option. Required when options is an array of objects.
renderOptionLabel(option) => ReactNode
Custom renderer for option labels. When not provided, the label is derived from the option value or the property specified by labelKey.
getOptionDisabled(option) => boolean
Function used to determine whether an option should be disabled. Return true to disable the option and prevent it from being selected.
radioPropsRadioProps
RadioProps passed down to each Radio component — custom color, size, etc.
formControlLabelPropsFormControlLabelProps
FormControlLabelProps forwarded to the internal FormControlLabel. Multiple fields can be configured using the ConfigProvider component.
labelReactNode
Label displayed for the field. Defaults to a human-readable label derived from fieldName, e.g. firstName becomes First Name
showLabelAboveFormFieldboolean
Whether the field label renders above the control. This control has no built-in inline label, so it defaults to true; pass false to hide the visible label (the accessible name is still applied).
Default: true
formLabelPropsFormLabelProps
FormLabelProps forwarded to the internal FormLabel. The id is managed by the component. Multiple fields can be configured using the ConfigProvider component.
hideLabelboolean
When true, hides the rendered field label while preserving accessible labeling where possible.
requiredboolean
Indicates that the field is mandatory by adding an asterisk symbol (*) to the form label and setting the relevant accessibility attributes.
errorMessagestring | string[]
Validation error for the field — pass a single message string, or a string[] when the field can fail multiple rules at once (every message is shown together). A non-empty string or array puts the field in an error state; undefined/''/[] clear it. Normalize your form library's error shape to this at the call site (e.g. an RHF FieldError via its .message). Use renderError to customize how the message(s) are rendered.
renderError(errors: string[]) => ReactNode
Custom renderer for the resolved error message(s), called only when the field is in an error state. Always receives a string[] — use errors[0] for the common single-message case, or map over errors when a field fails several rules. By default a single message renders as text and multiple messages render on separate lines.
hideErrorMessageboolean
If true, hides the error message text while keeping the field in an error state.
helperTextReactNode
Content displayed in the FormHelperText component below the field when there is no visible validation error.
formHelperTextPropsFormHelperTextProps
FormHelperTextProps forwarded to the internal FormHelperText. The id is managed by the component. Multiple fields can be configured using the ConfigProvider component.
customIds{ field, label, helperText, error }
Overrides the default field, label, helper text, and error IDs used for accessibility.

Playground#

Driven by plain React state — string and object options (labelKey / valueKey), getOptionDisabled, radioProps, a custom renderOptionLabel, and required validation.
