While working with a MUI dialog and MUI grid, I encountered an issue. The code I am using is directly from the website, with only minor modifications to the dialog function names and the box wrapping the dialog. Despite changing the size of the dialog, the grid items continue to display in a three-column layout instead of stacking to 12 at 'xs' screen size. I can't seem to figure out why this is happening as the code seems correct to me.
<Box sx={{flexGrow: 1}}>
<Dialog
fullWidth={fullWidth}
maxWidth={maxWidth}
open={openDialog}
onClose={handleCloseDialog}
>
<DialogTitle>Optional sizes</DialogTitle>
<DialogContent>
<DialogContentText>
You can set my maximum width and whether to adapt or not.
</DialogContentText>
<Box
noValidate
component="form"
sx={{
display: 'flex',
flexDirection: 'column',
m: 'auto',
width: 'fit-content',
}}
>
<FormControl sx={{ mt: 2, minWidth: 120 }}>
<InputLabel htmlFor="max-width">maxWidth</InputLabel>
<Select
autoFocus
value={maxWidth}
onChange={handleMaxWidthChange}
label="maxWidth"
inputProps={{
name: 'max-width',
id: 'max-width',
}}
>
<MenuItem value={false}>false</MenuItem>
<MenuItem value="xs">xs</MenuItem>
<MenuItem value="sm">sm</MenuItem>
<MenuItem value="md">md</MenuItem>
<MenuItem value="lg">lg</MenuItem>
<MenuItem value="xl">xl</MenuItem>
</Select>
</FormControl>
<FormControlLabel
sx={{ mt: 1 }}
control={
<Switch checked={fullWidth} onChange={handleFullWidthChange} />
}
label="Full width"
/>
</Box>
<Grid container>
<Box sx={{ flexGrow: 1 }}>
<Grid container spacing={{ xs: 2, md: 3 }}>
{Array.from(Array(6)).map((_, index) => (
<Grid item xs={12} sm={4} md={4} key={index}>
<Item>xs=2</Item>
</Grid>
))}
</Grid>
</Box>
</Grid>
</DialogContent>
<DialogActions>
<Button onClick={handleCloseDialog}>Close</Button>
</DialogActions>
</Dialog>
