How do I expand the label scroll?

I made a log print on the label, but there is a limit to scrolling down

It depends on where the Label is.
If it's in an arrangement, using a scrolling arrangement.

If it isn't inside a layout component, set the screen to Scrollable

label inside in the layout

You should give some more info. Show your design screen. Tell how you set your label or screen. Which is scrollable?

as I said, you can use a scrolling arrangement.

I like List Pickers for logging.

They don't eat up your screen space, and there is no limit to the number of elements you can add.

If you like Labels, insert new lines at the front instead of the end, for better visibility.
