Why does a space appear between the dropdown-toggle button and dropdown-menu? Is there a way to remove this space? The box-shadow currently conceals the gap, but it becomes visible once the box-shadow is eliminated. Here is the code snippet:

</html>Edit: adjusted CSS code to highlight the space for better visibility.
