[BUG] Responsive navbar with dropdown

[VigoKrumins]

Hello,

I just found out a bug. When you've created a navbar with dropdown links, when you select a link in the dropdown (form Mobile version), it doesn't select the link, but closes the collapsible dropdown.

Visual example:
| Link #1
| Link #2
| Dropdown
|_ Dropdown Link #1
|_ Dropdown Link #2

So, if you select the "Dropdown Links", it's closes the collapsible Dropdown, but not redirecting to the "Dropdown Links".
