I have a suspicion that the CSS transition from my Theme is not being applied to a styled component wrapped in another function, but I can't pinpoint the exact reason. I obtained the Basic MUI Dashboard theme from this source and here. Initially, integrating it into my project worked smoothly. However, to streamline the implementation of the original 'Dashboard.tsx' file, I refactored the 'Drawer' and 'AppBar' styled components into separate files. Below is the code for the 'Drawer' implementation in the initial demo; besides wrapping this code within a 'Sidebar' function, everything else remains consistent with a similar version for the 'AppBar'.
function Sidebar(open: boolean, drawerWidth: number, toggleDrawer: any){
const Drawer = styled(MuiDrawer, { shouldForwardProp: (prop) => prop !== 'open' })(
({ theme, open }) => ({
'& .MuiDrawer-paper': {
position: 'relative',
whiteSpace: 'nowrap',
width: drawerWidth,
transition: theme.transitions.create('width', {
easing: theme.transitions.easing.sharp,
duration: theme.transitions.duration.enteringScreen,
}),
boxSizing: 'border-box',
...(!open && {
overflowX: 'hidden',
transition: theme.transitions.create('width', {
easing: theme.transitions.easing.sharp,
duration: theme.transitions.duration.leavingScreen,
}),
width: theme.spacing(7),
[theme.breakpoints.up('sm')]: {
width: theme.spacing(9),
},
}),
},
}),
);
return (
<Drawer variant="permanent" open={open}>
<Toolbar
sx={{
display: 'flex',
alignItems: 'center',
justifyContent: 'flex-end',
px: [1],
}}
>
<IconButton onClick={toggleDrawer}>
<ChevronLeftIcon />
</IconButton>
</Toolbar>
<Divider />
<List component="nav">
{NavItems }
<Divider sx={{ my: 1 }} />
</List>
</Drawer>
);
}
export default Sidebar;
Further, in the 'Dashboard.tsx' file, the following code is present:
<ThemeProvider theme={mdTheme}>
//other components omitted
{Sidebar(open, drawerWidth, toggleDrawer)};
//other components omitted
</ThemeProvider>
The three props passed to 'Sidebar' are derived from the original demo (where 'open' signifies a state value, 'drawerWidth' defines the sidebar's width, and 'toggleDrawer' operates as a function to update the state). Despite implementing these changes and running the application, users can still toggle the drawer open and shut like in the original demo; however, the smooth transition evident initially seems to be absent, resulting in a rather abrupt opening and closing of the drawer.
I experimented with various implementations involving 'withTheme', 'useTheme', etc., but none appeared to yield the desired outcome. A related query implied that including 'position:relative' within the Drawer container was necessary, yet this parameter seems to be already incorporated during the 'styled' call (to the best of my understanding). Any assistance on this matter would be greatly appreciated.
