Automatically sizing a Widget to fit the children

[Lawrence Moore]

I'm trying to create a bubble widget which has various numbers of options depending on the circumstances in which it was clicked, but I'm having trouble sizing it properly.  Is there an easy way to automatically set the size to fit the children?  Thanks!

Usually it's best to use a GridLayout for the automatic sizing, with 'height: minimum_height' and 'size_hint_y: None' in its kv rule (or the equivalent with width for a horizontal version).

I don't remember how bubble works, but I guess either it will automatically resize to fit the gridlayout, or you can do that manually too.
