Hierarchy Position of lower level nodes

Hi Folks,

I have a requirement to display the lower level nodes of hierarchy to be opened from the above position not below.

Ex: Say i have hierarchy for the date field, when a user expand "Quarter 1" the nodes Jan / Feb / Mar showed be opened from above(left side) not below(right side).

Please note my source is BEx query and likewise the hierarchy is built in the BW. This can be addressed in the BEx report, there's an option in the query designer, please find the attached for the same. It works fine in the BEx report but with the same setting, it does not work in the WEBi report.

Any thoughts would be helpful.

Note - I'm on BO 4.1

Thanks,

Vinay
