I would like to show all the index entries from an element table in a Dropdown component.

The final goal is to be able to select a value from the Dropdown which then selects the according row in a Parameter table.

But I seem not be able to link/configure the Dropdown with a dynamic list of all the indices in the table.

I tried this using several ways (directly selecting the index column from the table or by using a GQI query), but I cannot get it to work. When I represent the same data as a Table or as a Parameter table I have the impression I am at least selecting the correct data set which could be used as input and represented as a Dropdown. But when I then change the Visualization to Dropdown I don’t see the values, but just some reference to a Query or Identifier name.

What am I missing here?
