Sub Menu

Hey guys, I would like to make a menu on my website with sub menus in it. For example, I would like to have a “BLOG” page menu and the Sub-Menus would be, let’s say Events/Occassion. So far I have went on Appearance > Menus and made the Events/Occassion the sub menus under BLOG but I want it so that when I click the BLOG page, It will list the sub menus on the page so you can click on it to go to the desired page (Click Blog>Desired Topic *Event*>List of all Events (e.g Fashion/Car/Birthday).

OR

Make it so that the Blog is unclickable and when you hover over it, it will list the sub menus. Thanks!
