Thank you for your response!
I have tried bi-era.com_listbox,Horizontal Listbox, Styled List as well but maybe I'm not setting the default selected value correctly.
As told earlier my dimension is monthname(trandate) where I have values like Jan 2017, Feb 2017....May 2017 etc.
On load, I want to display latest always and the user can clear filter to do a proper selection.
Thanking you in advance.
