 Use `FieldRoot` for each standalone named field. A field must have a stable `name`, a label relationship, and either a `FieldControl` or another control that participates in the same Base UI field context. Prefer a visible label for normal form rows; when the surrounding UI already supplies the visible text, use the matching label primitive visually hidden or put `aria-label` on the actual interactive control. `FieldDescription` and `FieldError` provide the message relationships that screen readers need, while the Dify wrapper adds the default Form Input Set styling from the design system.
 
-Choose the label primitive by the control semantics. Text-like inputs, input-based `Combobox` / `Autocomplete`, single `Checkbox` / `Radio`, `Switch`, and `NumberField` use `FieldLabel`. Trigger-based `Select` fields use `SelectLabel`; `Slider` fields use `SliderLabel`, with per-thumb `aria-label` only when the thumbs need distinct names. `SelectGroupLabel` and `AutocompleteGroupLabel` only label grouped options inside their popup content; they are not field labels.

 Use `FieldsetRoot` and `FieldsetLegend` when one field is represented by a group of related controls, such as checkbox groups, radio groups, multi-thumb sliders, or a section that combines several inputs. For checkbox and radio groups, wrap each option with `FieldItem` and give each option its own label:
