How to refer to checklist value

[gbethardy-h2oai]

How does one refer to the checklist values in code to control processing? For example if item 1 is checked perform some operation, if item 2 is checked perform another, etc.

Checklist is for gathering multiple selections, for single selections you might want to use checkbox instead. Maybe you are looking for something like:

@app('/demo')
async def serve(q: Q):
    if not q.client.initialized or q.args.show_form:
        q.page['example'] = ui.form_card(box='1 1 4 10', items=[
            ui.checklist(name='checklist', label='Choices',
                         choices=[ui.choice(name=x, label=x) for x in ['Egg', 'Bacon', 'Spam']]),
            ui.button(name='show_inputs', label='Submit', primary=True),
        ])
        q.client.initialized = True
    # Check if specified item is selected.
    if q.args.checklist and 'Egg' in q.args.checklist:
        q.page['example'].items = [
            ui.text('You have selected an egg! Make an omelette!'),
            ui.button(name='show_form', label='Back', primary=True),
        ]
    await q.page.save()

Or with checkbox:

@app('/demo')
async def serve(q: Q):
    if not q.client.initialized or q.args.show_form:
        q.page['example'] = ui.form_card(box='1 1 4 10', items=[
            ui.checkbox(name='checkbox1', label='Checkbox1'),
            ui.button(name='show_inputs', label='Submit', primary=True),
        ])
        q.client.initialized = True
    # Check if specified checkbox is selected.
    if q.args.checkbox1:
        q.page['example'].items = [
            ui.text('You have selected Checkbox1'),
            ui.button(name='show_form', label='Back', primary=True),
        ]
    await q.page.save()
