A DataGrid is created within Dialog. But the column menu is overlapped by Dialog.
Please check the following demo SandBox
What I have found and try so far:
The z-index:1300 will cover the column menu
<div role="presentation" class="MuiDialog-root makeStyles-dialogRoot-41" style="position: fixed; z-index: 1300; right: 0px; bottom: 0px; top: 0px; left: 0px;">
I have try to use classes={{ root: (z-index=0) }} in dialog component. But it still overwrited by 1300.
2.Clicking a column menu will create a tooltip list for selecting sorting action
<div role="tooltip" style="position: absolute; will-change: transform; top: 0px; left: 0px; transform: translate3d(217px, 137px, 0px);" x-placement="bottom-end">
If I add z-index=1500 in this tag directly in browser(F12). The menu will work fine. But I have no idea how to apply the CSS to this tag.
You can add style={{ zIndex: 0 }}
in your Dialog
component.
<Dialog
open={open}
onClose={handleClose}
maxWidth="md"
fullWidth
style={{ zIndex: 0 }}
>
