How do I add a dropdown column to my collection in PowerApps?

I have a gallery connected to an Excel table. I want to add some of the gallery columns to a collection. I am doing-

ClearCollect(Attgallery,ShowColumns(Gallery3.AllItems,"Name","Language","Mentor","Type",Dropdownatt.Selected.Value));

The last column that I am adding here is a dropdown value which is giving me the error. The dropdown is a new column which was not present in the Excel table. How do I add it to the collection?

Edit: I tried changing my code.

ClearCollect(Attgallery,ShowColumns(Gallery3.AllItems,"Name","Language","Mentor","Type"));
ClearCollect(Finalcollection,AddColumns(Attgallery,"Attendance",Dropdownatt.Selected));

Now the collection is getting created, but from the dropdown values only the last value that was selected is being assigned to every row of the collection.

Here is some pseudo code that shows an approach with ForAll:

clear( YourCollection );
ForAll(
  Gallery.AllItems,
  Collect( 
    YourCollection,
    ThisRecord.Dropdownatt.selected,
    ....

This links gives some information. Basically you should collect every row with it's associated dropdown value. ForAll is useful for this.
