I have 2 doubts regarding the "Input Control" functionality in BI4: 1) Can the Input Controls in BI4 be manipulated? I mean, can we change the IC display as BOLD or change the values from Italics to regular? Or change the colors? 2) How to get hierarchy type control in IC? Let's say my first IC is for Country and second is for State. If I select a particulat country from Ist IC,second one should show me states belonging to selected country. Is that possible? Thanks in advance!!!
