Difference between supress and hide

When we write ckick on the crystal report-insert-section we will have several option to choose but what is the difference between Hide(Driil=Down ok) and Supress(No Drill-Down)??
I tried the help but I did'nt get the idea...good question!!! I've already search that but still no answer. They are the same in function, the only difference is the group tree when you view the report.|||I thought the help was quite clear - suppress if you don't want it at all, hide if you don't want it displayed initially but do want to be able to click on the item in the group tree and see the data therein.|||Ok,Igot the point:
if ur secton detail is between a group header and a group footer ,when u hide the section detail at run time if u double-click a ligne u will have the detail but if u supressed u will not have the detail,,try it u will understand better....
