Hi All: I am freshman in Jasper, thanks for your reply in advance. I have one 'single select query' input control, but there are too many entries (over 50,000) in this dropdown, so it is very slow. So I would like an on-demand dropdown, such as firslty load first 10000, then load another 10000 with sroll-down by users...; or implement it as an editable dropdown, then users do not need to sroll down to find one entry and he can direclty type one. Thanks for your reply. Post Edited by leiwang2012 at 04/10/2012 13:07
