Datasource dimensions in Listbox/Dropdown

Hi,

I want to create a listbox or dropdown box which lists all the Dimensions (NOT MEMBERS) of a data source. Also, is there a way to show the filtered items from a filter panel in the crosstab. For example if I choose product1 from filter panel and submit it, I want to be able to show product1 as a row in the crosstab.

Regards,

Swaroop
