Hi Tomas,
Thank you for contacting Syncfusion Support.
In Syncfusion CardView control, the items are aligned one by one. We have prepared a sample for your reference and it can be downloaded from the below link.
Could you please confirm you need the items in single line horizontal alignment only and provide more details about your consolidated requirement? It will be helpful us to provide prompt solution as earlier as possible.
Regards,
Venkateshwaran V.R.
