Select a new value in the list to reset the value in the control. If you bind the combo box to a field in the underlying table or query, you can change the value in the field by selecting a new value in the list. If you bind the combo box to a multi-value field, Access displays the list with check boxes to allow the user to select multiple values. You can bind multiple columns to the list, and you can hide one or more of the columns in the list by setting a column’s width to 0. You can bind the actual value in the control to such a hidden column. When a multiple-column list is closed, Access displays the value in the first column whose width is greater than 0. Access displays all nonzero-width columns when you open the list.
