Labels provide accessible text descriptions for form fields.

​
Basic Usage

Labels can contain text directly or wrap other components.

​
With Form Fields

Labels are typically paired with inputs and other form controls:

​
Optional Indicator

Set optional=True to show a muted “optional” hint after the label text. Form.from_model() sets this automatically for non-required fields; for manually built forms, set it yourself on any label.
