Prompt Type ('Select Value') not working

[Naven]

Hi,

I have a requirement to show the value prompt drop down in Query Studio when user drags and drops a query item to filter the values.

I have created a filter in the query subject present in FM and published the package.When I drag the query item in Query Studio it prompts me enter the values and run the report but I need to display a prompt where it shows list of values(drop down or check box)so that I can select necessary values available in the list. Also I tried changing the proprties of Query item in Prompt Type to 'Select Value'  but it is not working, again the same default text box prompt is appearing.

Thanks,
Naven
