I am using Extjs 6.5.3. I have grid with row expander. I want combination of row editor and row expander. And when I click on the row it should open row expander and allow all rows in row expander to be edited along with the main row. And all rows should be updated at once, means if I updated 1st row and from row expander 2nd and 3rd row then that all rows should be updated on one click of update button of row editor.
Please help.
