Hi,  
the documentation states that instead of a single property string also an array containing more then one property string could be used.

However, I cannot find an example showing this possibility.

e.g. if I have property “name” and “position” in the json schema as items in an array, how would the assignment look like?

In the UI schema I tried without any effect:  
`"elementLabelProp": ["position", "name"]`

referencing only one property in an array works well, like  
`"elementLabelProp": ["position"]`

Any suggestions?

Hi @anotherUser,

The “array” variant of the `elementLabelProp` is used for specifying a path to the property. So `["position", "name"]` will try to resolve `position.name` of the object.

Our off the shelf renderers can only show one property of an element in the title. If you like more control then you can use a custom renderer in which you can render arbitrary UI including as many properties as you need.

Thank you @sdirix for clearing this up! 🙂
