Hi marceloobrito11e0, welcome to Thunkable! 
Be sure to check out our posts about How to ask Great Questions v2.0, our Community Guidelines, and our Docs as you get started.
There are two things to consider here: Items in a data viewer each have a row ID attached to them
and if you are using a data viewer, you’ll have to connect a data source. So you can use that Row ID and the data source blocks to populate the data on the specific page.
Our Thunkable Academy uses a similar idea with an employee directory app. I would suggest taking a look at it and basing the logic of your app off of the employee directory.
Happy Thunking!
