Combo, show additional fields from a table

The table contains multiple fields, but only one field is displayed in lightbox.
example:

$combo->dynamic_loading(10);
$combo->render_table(“cb_data290”,“id”,“f4710”,“f4910”);

in field “combo” of lightbox displayed only f4710(name of person), but f4910(birthday) not displayed in lightbox.
How fix it?

Combo connector allows to load only a pair of option_id and option title.
