Add Navigation Dropdown Menus in WordPress with BootStrap v4

I decided to consolidate some of the links in my navigation bar at the top (header) of my site. This eliminates the need for individual web pages that are full of links. Essentially, you will get to where you want to go quicker with less scrolling. Mobile device users will appreciate this the most! They can quickly tap the drop down menu of their choice and then tap one of the links the drop down menu provides. I decided to create a drop down menu for my “work samples” link and for my “background” link. In my custom WordPress theme, the current navigation bar is located in the header.php file.
View the source code of a page with Ctrl + U. You will see the “Navigation” section of the page or you can refer to the pic below.

The area of interest here is the div with the “dropdown show” class. Another div drop down menu is located in this div container. The main link is set to “” so the browser will remain on the page if clicked. When clicked, three links will show up below and will be available to select. The two div containers are then closed. All of this is contained within a list class “nav-item” for BootStrap to change it accordingly.

The drop down menu is in effect and will look great on any device!
