This is the sixth menu item that appears under the Trips icon
The Keyword section under the Destinations section in the dashboard menu lets you add a new Keyword to the list. It allows you to add the keyword and the newly added keyword will be listed on the right-hand side of the page.
You can assign the keyword to the individual trip post by going to the individual trip post edit screen.
The process of adding the keywords and assigning them to the trips is the same as you add the category and assign them.
