Hello All.
Im new here, my apologies upfront if this has been ask before but hopefully you can help me out though. 
I was wondering if it is possible to achieve getting a hierarchical view on my webi report without stablish such herarchies on my backend, and create that behavior on my frontend, I don't have acces to the backend so I'm only able to obtaing the values as attributes when the query is been desing, therefore it prevent me to create a hierarchical behavior on my report, but is there a trick or a way to get the same view with the expand/collapsed buttons even though I lack the hierarchies on my query?
Also I noticed that I can get a similar drill behavior by using outline but this is not working correctly for me, because, yes I'm able to break the data on my report and collapsed the information, but once I collapsed everything there's is no way, at less that I have try, to expand it again.
I know this probably is an old issue, me being new at it, but if somebody can point out a solution or old threads that can help me out Il' appreciate it.
