Low code usage

This component can be declared directly in Python, using backend-driven UI.

python
ui.TextareaInput(content={
        "label": "", # str 
        "placeholder": "", # str 
        "rows": 0.0, # Union[float, str] 
        "cssClasses": "", # str 
    },
    handlers={
        "ss-change": handle_event,
        "ss-change-finish": handle_event,
    }
)
A function, in this example handle_event, should be implemented in your code to handle events.
python
def handle_event(state, payload, context, ui):
  pass
