How to create an inetractive object where you can click and see the properties that you defined?

I would like to have a csv sheet that has a property for different objects in Unreal, when I click on an element i can see the property associated to that object.

this table could be used via a plug in.

has someone tried that before?

You can do something like this using Data Tables in UE4, which is pretty similar to a CSV you might use. You can read about data tables all over the place, but once you have created one, you can use ‘Get Data Table Row’ along with a few other functions from blueprints in order to achieve what you want.
