[Erp5-users] Filter in listbox

[Vera Kurpas]

Is it possible to filter listbox' rows  which have different value in
the same field? 
 For example there are some rows in Organization listbox with value_1 in
the field "Activity" and some rows in the same listbox with value_2 in
that field and many rows with other values in the field. How can be
filtered rows having value_1 and value_2 in the field "Activity"? The
listbox is large and it's difficult to mark the rows by hand before
using button 'Filter'.
