What theme are you using?

core

Is your feature request related to a problem? Please describe.

Consider the schema bellow :

{ "title": "Confirmation", "description": "Please to confirm this value is foo", "type": "string", "const": "foo" }

My expectation is to render this schema as a checkbox (two states : value is "foo" = checked or value is empty = not checked), but that behavior is not allowed in UI schema in accordance with the doc.

Describe the solution you'd like

String field with const constraint should be able to be render as checkbox :

  • Value attribute should be set as const constraint
  • If checked, model should be updated based on value attribute
  • If not, property is removed from the model

Describe alternatives you've considered

研究方向
The issue requires modifying the checkbox widget to support string fields with a 'const' keyword. Check the existing CheckboxWidget in the core theme (likely in packages/core/src/widgets/CheckboxWidget.tsx) to see how it currently only handles boolean schema types. The fix should allow the widget to be used when the schema has type: 'string' and a const value, using the const as the checked value and removing the property when unchecked. Additionally, review the handling of 'const' in the form state management to ensure proper property removal.
