How do i send request to server with post method when using a HTML menu

Question

there is a menu with 5 select key in my HTML program . By clicking each of these keys a request should send to server . I use 'a' tag and href for this . by this approach i have to send request with GET method but i want use POST . For sending request by POST , I use 'form' tag for each of these keys . so for 5 key i use 5 'form' tag . Is this a common and acceptable way? haven't i any better way for sending request with POST? thanks

Answer 1

<form method="POST" action="YOUR_BACKEND_URL_ENDPOINT">
    <select name="YOUR_FIELD_NAME">
        <option value="VALUE_1"> VALUE_1_NAME </option>
        <option value="VALUE_2"> VALUE_2_NAME </option>
    </select>
    <button type="submit">Submit form</button>
</form>

I guess this should work.
