Form groups encapsulate components related to a single form input. At a minimum, it should contain ControLabel
and FormControl
child components. Many FormGroup
properties will be transformed or passed along to its children so these values will not need to be manually re-specified. NOTE: Checkbox
controls are not allowed inside FormGroup
as they are self-labeling.
Three sizes are supported: 'lg'
(the default), 'md'
and 'sm'
. Use the size
property to set the size.
Note the use of the FormGroup.HelpBlock
component to provide additional explanatory text in the following example.
Use the required
property to mark form controls as required. Labels will display a visual indication while input controls will have a required
attribute added to help with assistive technologies.
Validation state properties apply only to FormGroup
components (not individual ControlLabel
or FormControl
components). The validation tooltip will be triggered when hovering over the icon next to the ControlLabel
and also when the FormControl
receives focus. Use the validationMessage
property to set a validation state.
