Why is the MuiThemeProvider overriding a component style?












0















I have an outer component that uses MuiThemeProvider:



<MuiThemeProvider theme={full_theme_e}>
<div>
<AppBar />
<Filter />
</div>
</MuiThemeProvider>


In my filter component I define a custom style:



const styles = {
expansionPanel: {
borderTopLeftRadius: 0,
borderTopRightRadius: 0,
borderBottomLeftRadius: 0,
borderBottomRightRadius: 0,
}
};


Apply to the component:



<ExpansionPanel className={classNames(classes.expansionPanel, className)}


And use the style in my export:



export default withStyles(styles)(Filter);


The problem is my custom style gets overwritten by the MuiThemeProvider, why?
Chrome showing style being overwritten
