There are a lot of "Title" fields on the page, which is which?
In general speaking, the Title field is the main title of the page. Navigation Title, Page Title, and Subtitle fields are all reserved for the frontend display purpose.
The page's title is too long for the navigation, what can I do?
If the Title of the page is too long to display for the main nav, you can set up a shorter title in the Navigation Title field. Simply fill out the shorter title in the Navigation Title field and system will display that instead of the Title. If you want to revert it back to the original Title field, simply remove the text in the Navigation Title field.
