If value is a callable, run the function 'every' number of seconds while the client connection is open. Has no effect otherwise. The event can be accessed (e.g. to cancel it) via this component's .load_event attribute.
variant

Literal[('primary', 'secondary', 'stop')]

default: "secondary"

'primary' for main call-to-action, 'secondary' for a more subdued style, 'stop' for a stop button.
size

Literal[('sm', 'lg')] | None

min_width

int | None

default: None
