In PHP, what is the difference between a combination field and a select field?

In PHP, a combination field allows users to input their own values, while a select field provides predefined options for users to choose from. To implement this, you can use a combination of an input field and a select field in your form. You can use JavaScript to toggle the visibility of the input field based on the user's selection in the select field. 

<form>
    <select name="options" id="options" onchange="toggleInput()">
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
        <option value="other">Other</option>
    </select>
    <input type="text" name="other_option" id="other_option" style="display: none;">
</form>

<script>
    function toggleInput() {
        var select = document.getElementById("options");
        var input = document.getElementById("other_option");
        
        if (select.value == "other") {
            input.style.display = "block";
        } else {
            input.style.display = "none";
        }
    }
</script>
