Index Dropdown Bulletin For Free

We use the selectedIndex property in JavaScript to show the index of the selected option in a dropdown list. We use the id of the dropdown list to access the element using JavaScript and then call selectedIndex on it to get the index of the selected option in the dropdown list.
