Adding a class directly to the input element is what I am trying to achieve here.https://i.sstatic.net/qGGwD.png
The class MuiInputBase-input needs to be added. This code pertains to a date picker.
import { DateTimePicker, MuiPickersUtilsProvider } from "@material-ui/pickers";
render() {
return (<MuiPickersUtilsProvider utils={MomentUtils}>
<DateTimePicker value={this.state.selectedDateTime} onChange={this.OnChangeHandler} className="mh-Dateinput" />
</MuiPickersUtilsProvider>)
}
