Make name attribute mandatory for select tag.

[BTWS2]

The name attribute is not strictly required in an HTML <select> element. However, if you want to send the selected value when the form is submitted, the name attribute is essential. Without the name attribute, the selected option's value won't be included in the form submission data.
