While working with Extjs grouping grid. I would like to hide and show the Expand/Collapse button in Grouping grid group header. but i don't want to global for all grouping grid.
So i added custom CSS for my particular grid.
Recently i found the top support tip from Kevin Cassidy.

Basically it will render like this
We need to add the CSS class config option. to number filed.
