combobox: how can allow select multiple values in a field

[andrea]

I setup a combo box for lookup value. How can I allow
user to select multiple values from a scroll down list.
Only list box has the Multi Select property, how can I
add that to a combo box??

The combo box does not allow multi-select. Since the combo box has to be
opened to view the list, it would be a very horrible user interface anyway,
as the user would not really be able to see what have been selected.

It is not clear if you are trying to save those multi selects, but if you
are, then you likely need to use a sub-form in continues mode.

You can't: combo boxes, by design, do not allow multiselect.
