}

.card.hover:hover {
    background-color: var(--lumo-contrast-10pct);
}

The backend part is a bit more complicated and will follow on occasion :slight_smile:

I hope I could inspire you for a session page.

Have fun putting it into practice :slight_smile:

Is that Cards in a list? How did you use a data source?

Because Vaadin/JMIX stores Sessions inside an Array, I don’t use a DataSource (Just a forEach Loop).

The Card is appended to a VerticalLayout.

Thanks.
Did you consider this option dynamically switched between desktop user and small device users?

As I tested it in JMIX 2.3 there were no responsive problems on mobile devices.
