Is it advisable to use a select box for selecting from 150 recipients in a contact form, and how can this be achieved in PHP?

Using a select box for selecting from 150 recipients in a contact form may not be the most user-friendly option as it could lead to a long and overwhelming dropdown list. Instead, consider implementing a search functionality or pagination to make the selection process easier for the user.

<select name="recipient">
    <?php
    // Assuming $recipients is an array of 150 recipients
    foreach ($recipients as $recipient) {
        echo "<option value='" . $recipient['id'] . "'>" . $recipient['name'] . "</option>";
    }
    ?>
</select>
