How does the chainedSelectors class handle updating the second selector based on the selection made in the first selector?

To update the second selector based on the selection made in the first selector, we can use JavaScript to listen for changes in the first selector and update the options in the second selector accordingly. We can achieve this by creating an event listener for the change event on the first selector, then updating the options of the second selector based on the selected value of the first selector. 

<script>
document.getElementById('firstSelector').addEventListener('change', function() {
    var firstSelectorValue = this.value;
    var secondSelector = document.getElementById('secondSelector');
    
    // Clear existing options
    secondSelector.innerHTML = '';
    
    // Add new options based on the selected value of the first selector
    if (firstSelectorValue === 'option1') {
        var option = document.createElement('option');
        option.text = 'Option A';
        option.value = 'optionA';
        secondSelector.add(option);
    } else if (firstSelectorValue === 'option2') {
        var option = document.createElement('option');
        option.text = 'Option B';
        option.value = 'optionB';
        secondSelector.add(option);
    }
});
</script>
