Provide isAlign to Navbar Dropdown

[stanonyime]

Thank you for this great project. It will be nice to have more options for the Navbar dropdown to allow aligning it either to right or left. I have a use case for having the dropdown as a child of a NavBarEnd. It currently projects beyond the viewport

Sorry for late answer. I'm unable for a moment (maybe one month) on working on this... If you want you can provide an example of the API for NavBar Dropdown and make a PR, or only with the first so anyone can jump on it :)
