Hi Ibrahim Aly,
List view will show list of objects from an entity,that means in the above mentioned picture have three rows represents three objects and that will increase when Load more option is clicked
You have successfully added three attributes(Title,Duration,Price).If you want Title,Duration,Price on next by lines then make the Alignment to left by adding the text widgets to each of the attribute.
If you added the attributes via ADD ATTRIBUTE button then its means appending the attributes on the displayed text
If you want to add new attributes to the entity in Studio then you must add the new attribute in Domain Model
Hope this helps!
