I need two textbox from TextField from MaterialUI one that can only enter alphabets(small or capital can also include spaces {Example : Risha Raj} as first textfield) and other one is also except only alphabets (small or capital) but with maxLength with only 3

so I did the following

           <TextField
            id='Product Name'
            label='Enter Student  Name'
            name='sname'
            value={values.sname}
            onChange={handleChange}
            error={errors.sname}
          />
            <TextField
            id='section'
            label='Enter Class Section'
            name='ccode'
            inputProps={{maxLength:3}}
            value={values.ccode}
            onChange={handleChange}
            error={errors.ccode}
          />

I am able to restrict the length but unable to do the alphabets
