Possible to expand multiple rows at the same time ?

[cuongnguyen112]

I am trying to expand the table row with BaseRowExpansionRenderer from this tutorial: 

https://dev.splunk.com/enterprise/docs/developapps/visualizedata/displaydataview/howtocreatecustomta...

But whenever i expand 1 row, the other opened one will closed

Is it possible to expand multiple rows at the same time (currently only one row expandable at a time)

Thank you very much !
