Hi all,
I need to add some custom css for the TwinColSelect, because if nothing
is selected the two selects don't align. That's probably some local problem in my
installation. However it can easily be fixed by increasing the min-height.
I can add a custom class in my yaml definition with styleName, that works
fine. But I don't know how to inject the css file.
The VAADIN solution ist to add a @StyleSheet, but I think it must be used in a suitable
class.
I need a hint how to do this.
Thanks for any help,
Heike
