Here is an image showcasing the current header render. The header consists of a HeaderMenu and 3 Links. While the links are functioning properly, the HeaderMenu is causing the links to be positioned below it. The HeaderMenu includes a div that wraps a Button and Popper, creating a dropdown menu.
I'm uncertain if this design structure is ideal, but for the styling aspect, I use a styles.js file from which I extract styles. These styles are then passed down as props to the smaller components for rendering. Hence, the components here have a 'classes' prop coming from useStyles in index.js.
Header.js
import { AppBar, Button, Link, Toolbar, Typography } from '@material-ui/core'
import HeaderMenu from './HeaderMenu.js'
const Header = (props) => {
const { classes } = props
return (
<AppBar position="static" color="default" elevation={0} className={classes.appBar}>
<Toolbar className={classes.toolbar}>
<Typography variant="h6" color="inherit" noWrap className={classes.toolbarTitle}>
Company name
</Typography>
<nav>
<HeaderMenu classes={classes}/>
<Link variant="button" color="textPrimary" href="#" className={classes.link}>
Here
</Link>
<Link variant="button" color="textPrimary" href="#" className={classes.link}>
Enterprise
</Link>
<Link variant="button" color="textPrimary" href="#" className={classes.link}>
Support
</Link>
</nav>
<Button href="#" color="primary" variant="outlined" className={classes.link}>
Login
</Button>
</Toolbar>
</AppBar>
)
}
