For using the row context menu, you have to specify
renderRowContextMenu. This function prop is called with
menuProps as a first param. Either modify those props and set the desired
items on the
menuProps (and return
undefined), or return a
<Menu /> component you want to render.
If
undefined is returned from the
renderRowContextMenu function prop, the default Menu is rendered (beware, it has no
items by default).
The second param passed to the
renderRowContextMenu function prop is an object with
{ rowProps, cellProps, computedProps, computedPropsRef }, where
rowProps are the props of the clicked row,
cellProps are the props of the clicked cell,
computedProps are the computed props of the
<ReactDataGrid /> and
computedPropsRef is a ref to the latest
computedProps object.
