Multi-select: display only one field of the drop-down query

[Sparkblender]

Hello!

I've configured a multi-select drop down to display two values in the look-up, like so:

The drop-down lookup displays the concatenated "Name" and "Alpha" fields, as expected.
When a value is selected from the drop-down, the concatenated result is shown, like so:

Nevertheless, I'd like to display only the "Alpha" field in the selection, e.g. the "en" and "fr" instead of "English en" and "French fr" respectively. Is this possible? How can I achieve this result without having to sacrifice showing the "English" and "French" texts in the dropdown?

Thanks.

You need to use 'Custom Dropdown Layout'.
In the HTML Template have the Attributes you want displayed in the Dropdown Panel.
In the Attributes to Display select those which should appear for a seleted Instance in the Dropdown Field.
