from typing import Optional
from h2o_wave import main, app, Q, ui


def get_form_items(value: Optional[str]):
return [
ui.text(f'date_trigger={value}'),
ui.date_picker(name='date_trigger', label='Pick a date', trigger=True),
]


@app('/demo')
async def serve(q: Q):
if not q.client.initialized:
q.page['example'] = ui.form_card(box='1 1 4 5', items=get_form_items(None))
q.client.initialized = True
else:
q.page['example'].items = get_form_items(q.args.date_trigger)
await q.page.save()
