Nested grid with GXT 3.0
I'm currently evaluating GXT for my company. We need to develop a webpage with a complex layout, actually a grid containing nested grids for a total of 4 sub-levels, each grid having different columns.
I looked at the Grid component and its expander capabilities, but expanders only output regular HTML and cannot take widgets as inputs. I did find a project called kevinjqiu/gxt-widget-expander, but it's only compatible with GXT 2.1.
What would be the most efficient and clean way to have nested grids with GXT 3.0?
Thanks in advanced for the answers.
