Hey.
1.
“Is there an easy way to change the menus to drop down menus that open with the title of the menu is clicked?” – You would need a plugin that adds that type of menu. I’m not aware of a plugin that does have this through.
2. h1 generally used of page/post titles.
h2 used on blog list pages for the post titles.
h3. Used for widget titles
h4, used for posts titles shown on the home page
Any of these can of course be used in your page/post content if you set it to.
Is there a specific place you have a question?
