dropdown is a component that shows a dropdown menu.
It must be placed inside a group element of the menubar that you will find at the top of your page in a header slot
This component accepts as entry a series of link. If the linked page does not exist, it will be rendered in red.
If you want to hide a dropdown if the size of the screen is too low, you can use the Bootstrap conditional display class
Example: show the dropdown above the lg screen width (992px)
