Code:
<select name="country">
<option value="1">Germany</option>
<option value="2">France</option>
<option value="3">Italy</option>
<option value="4">Korea</option>
<option value="5">China</option>
<option value="6">Japan</option>
</select>
I like to put a vertical space between Italy and Korea.

The code below can make a vertical space between Italy and Korea, but it goes to next page when a user clicks the submit button.
Code:
<select name="country">
<option value="1">Germany</option>
<option value="2">France</option>
<option value="3">Italy</option>
<option value="3">Italy</option>
<option valu"0">vertical space</option>
<option value="4">Korea</option>
<option value="5">China</option>
<option value="6">Japan</option>
</select>
I like to make a vertical space visually and it doesn't go anywhere when a user selects (4) option and clicks the submit button.
