Changing Menu Order on Collapsed Navbar in Bootstrap 3 - html

Question

I have a Bootstrap 3 Navbar that has two right-justified <ul> sections which gives me this:
When the menu is collapse for mobile, I get this:
I have two questions related to the collapsed menu. 1) How can I get the buttons to appear at the bottom of the collapsed menu instead of the top? 2) How can I change the styling of the buttons in the collapsed menu (without affecting the style in the horizontal menu)?
Below is the markup for this Navbar. And yes I have a reason for having two separate <ul> sections:
<div class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button class="navbar-toggle" data-toggle="collapse" data-target=".navHeaderCollapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>

</div>
<div class="collapse navbar-collapse navHeaderCollapse">
<ul class="nav navbar-nav navbar-right">
<li>Button One</li>
<li>Button Two</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li>Item1</li>
<li>Item2</li>
<li>Item3</li>
<li>Item4</li>
</ul>
</div>

Answer 1

I ended up finding a simpler solution for the reformatting and reordering of the button links on the collapsed navbar, one that doesn't require new javascript code:
<div class="collapse navbar-collapse navHeaderCollapse">
<ul class="nav navbar-nav navbar-right hidden-xs">
<li>Button One</li>
<li>Button Two</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li>Item1</li>
<li>Item2</li>
<li>Item3</li>
<li>Item4</li>
</ul>
<ul class="nav navbar-nav visible-xs">
<li><a href="#" >Button One</a></li>
<li><a href="#" >Button Two</a></li>
</ul>
</div>
I simply duplicated the Button One and Button Two <ul> section and added it to the bottom. I then removed the classes and ID on the <a> links so that no button formatting would occur. Finally, I added the hidden-xs bootstrap class to the top <ul> and visible-xs to the bottom <ul> class. That did the trick:

Answer 2

I ran into a similar issue but have been using Bootstrap 4.4 and this can be solved with a simple d-none d-block solution.
<ul class="nav justify-content-center">
<li class="nav-item d-sm-none d-md-block">
<a class="nav-link" href="#">Item 1</a>
</li>
<li class="nav-item d-sm-none d-md-block">
<a class="nav-link" href="#">Item 2</a>
</li>
<li>
<li class="nav-item">
<a class="nav-link" href="#">Item 3</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Item 4</a>
</li>
<li class="nav-item d-none d-sm-block d-md-none">
<a class="nav-link" href="#">Item 1</a>
</li>
<li class="nav-item d-none d-sm-block d-md-none">
<a class="nav-link" href="#">Item 2</a>
</li>
</ul>
Using this method allows for items 1 and 2 to only appear after the display is set to small and below. While also hiding the originals at that same display size.
