Hide groups as default

Hey all!

I have what I’m hoping is a pretty simple question - as per the image below, I have ‘nested columns’ which I’ve grouped.

When I add a new item, it displays all the info (as per ‘Breakfast’ on the final row), whereas the desired behaviour is to have them hidden/collapsed, i.e. like the other items above.

Is there a way to achieve this?

Thanks so much!!
