It’s a basic question, I’m trying to leave the default value empty, but it always ends up filling with the first item:
<TextField
select
id="letter"
name="letter"
label="Letra"
defaultValue=""
SelectProps={{
native: true
}}
variant="outlined"
margin="normal"
fullWidth
>
<option key={1} value={1}>
A
</option>
<option key={3} value={2}>
B
</option>
<option key={3} value={3}>
C
</option>
</TextField>
