I have created the list box as month,year. when the user click clear button, it should make the list box to default selection like current month and year.
I have done that in trigger present in document properties.
Document properties - > trigger -> on any select -> select in field -> Month ->if(getselectedcount(Month)=0, maxstring(Month),Month)
It is working fine. but i cannot able to multi-select two or more months in list box.
How to make the multi selection possible in the list box?
