You are looking at an HTML rendering of the generated widgets, they are lacking responsiveness due to no Python kernel being available for callbacks.

Form from JSONSchema

Use a raw JSON Schema document to generate a form with validated defaults.

from ipywidgets_jsonschema import Form

schema = {
    "type": "object",
    "properties": {
        "experiment_id": {
            "type": "string",
            "pattern": "^EXP-[0-9]{4}$",
            "default": "EXP-0001",
        },
        "replicates": {"type": "integer", "minimum": 1, "maximum": 10, "default": 3},
        "mode": {"type": "string", "enum": ["fast", "accurate"], "default": "fast"},
        "temperature_c": {
            "type": "number",
            "minimum": -20,
            "maximum": 120,
            "default": 22.5,
        },
        "send_report": {"type": "boolean", "default": False},
    },
    "required": ["experiment_id", "replicates", "mode", "temperature_c", "send_report"],
}

json_schema_form = Form(schema, use_sliders=True, show_descriptions=True)
json_schema_form.show()

json_schema_form.data

{'experiment_id': 'EXP-0001',
 'replicates': 3,
 'mode': 'fast',
 'temperature_c': 22.5,
 'send_report': False}
