dropdown box restriction

Hi all,

We have on the wbt one dropdownbox based on 0CALMONTH. In the data provider there is also planning data, so in the dropdownbox there are values:

....

05.2010

06.2010

12.2010

I'm wondering if it's possible to restrict the data in the checkbox till the actual month.
