First of all Hi, I am new to this community and am learning DNN along with bootstrap and Css. 

Now, I installed a theme called Hammerflex on my website and began customizing it to look a certain way. Everything was going great until I tried to access the dropdown menu  of a page. I moused over the navbar page containing the dropdown menu and nothing appeared. I have tried and I cannot figure out why this dropdown list isn't showing the items. I tried another theme and the dropdown works, but I would kill myself if I had to start again. Can someone help me?
