Are there any plans to implement multiselect for TreeGrid mode? As far as I can see it is still not implemented, right?
Or maybe someone can suggest some kind of workarrond (for example separate column with checkboxes with onclick events which will allow to select correspondent TreeGrid rows, is that possible)? That is very required for our project.
Sorry, my previous post was a little bit wrong. I had bad understanding of what is TreeGrid. Actually for our project we need rows grouping by columns: /blog/?page_id=393/feature-request/line-grouping-nesting-breaking/#p10410
