I almost forgot that. But while I was having another look to gtk-demo, I found
the solution ! It's in 'Combo boxes' and it can be easily adapted to
Gtk2-Perl. Here is the code I needed:


$combo->set_cell_data_func($renderer, sub {
    my ($layout, $cell, $model, $iter) = @_;
    my $sensitive = !$model->iter_has_child($iter);
    $cell->set('sensitive', $sensitive);
});


I can't tell you why it also hide the title, but it works just as I expected.

I posted this solution to have it in the archives if someone else needs to do
the same.
