I'm trying to use the Expand cell renderer example
1: https://mui.com/components/data-grid/columns/#RenderExpandCellGrid.js provided in the documentation while using data-grid-pro. It started to behave strangely after I added pinned columns:
<DataGridPro
rows={rows}
columns={columns}
initialState={{
pinnedColumns: { left: ["col2"], right: [] },
}}
/>
- For pinned columns, the popper is displayed bellow the cell:cut-off popper
- When I move over cells, all the lines I moved over stays selected: 3 selected rows
I'm looking for a solution to implement both column pinning and Expand cell renderer
did you try to modify the
z-index
of the proper such that it appears on top of the pinned column?
