Adding list of values in ModelBuilder using ArcGIS Pro

Question

I'm searching for the option to use lists in a model of the ModelBuilder under ArcGIS Pro. In ArcMap 10.X, I could right-click on the variable - properties - and under "this variable contains" change the toggle to "A list of values". I cannot find a similar function in ArcGIS Pro.

I explicitly do not search for iterators!

In ArcMap it looked like this: enter image description here

When you add a variable to the model you need to tick on Multiple values as shown below.

• xmisx: thanks a lot. But how can I make this a list of input variables. I can only set the new multi values-variable as a precondition for a tool but not as input. I'm not sure if this is exactly what I was looking for. I added an image to my original post.
• Hornbydd: As you have not explained what the Puffer tool is and what its input requirements are then I can only guess that you need to set the data type for your variable?
• xmisx: ah sorry, "Puffer"-tool is simply the "Buffer"-tool which is called "puffer" in German language. Sorry, that I did not gave you all the information but the image above is just an example of lists. Thanks!
