Issue with Flat-UI: Navigation bar is not collapsing correctly. Need help to resolve this problem

I am currently utilizing the most recent Twitter Bootstrap along with Flat UI. I have been trying to create a basic navbar that collapses when the screen size is reduced. How can I resolve this issue?

This is how it currently appears:

My navigation items only become visible when I click on the 'toggle navigation' button.

Below is the HTML code for my navbar, directly copied from the Flat-UI components page:

<div class="container">
  <nav class="navbar navbar-default" role="navigation">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="brand" href="#">Brand</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>

      </ul>

      <ul class="nav navbar-nav navbar-right">
        <li><a href="#">Link</a></li>

      </ul>
    </div><!-- /.navbar-collapse -->
  </nav>
</div>

Answer №1

I encountered a similar issue, but managed to resolve it by taking the following steps:

  • First, I downloaded the latest version of the Flat UI from GitHub
  • Next, I confirmed that it was utilizing Bootstrap 3 in the /boostrap/css directory
  • I then proceeded to copy all CSS files to /vendor/assets/stylesheets
  • Similarly, I copied all JavaScript files to /vendor/assets/javascripts
  • All images were also duplicated to /vendor/assets/images
  • And the fonts were stored in /vendor/assets/fonts
  • I adjusted my /assets/javascripts/application.css.scss as follows:

application.css.scss

*= require ../../../vendor/assets/stylesheets/bootstrap.css

*= require ../../../vendor/assets/stylesheets/flat-ui.css

*= require ../../../vendor/assets/stylesheets/demo.css

*= require_self

*= require_tree .

*/
  • For the Javascript, I modified my /assets/stylesheets/application.js like this:

application.js

    //= require turbolinks

    //= require ../../../vendor/assets/javascripts/jquery-1.8.3.min.js

    //= require ../../../vendor/assets/javascripts/jquery-ui-1.10.3.custom.min.js

    ... (remaining scripts listed)

    //= require_tree .
  • To enhance the layout, I added a basic bootstrap markup to layouts/application.html.haml
... (content for application layout)

By following these instructions, I was able to achieve the desired outcome.

Note: It is vital to update references to files in vendor css/js as they may break in production. Changing extensions to .scss and adjusting URLs appropriately will help prevent issues.

The only tweak I'd suggest is shifting the .container inside the .navbar. Everything appears to be functioning smoothly in this setup:

http://jsfiddle.net/Lk3AZ/

<nav class="navbar navbar-default" role="navigation">
    <div class="container">
    <!-- Brand and toggle get grouped for better mobile display -->

    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="brand" href="#">Brand</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>

      </ul>

      <ul class="nav navbar-nav navbar-right">
        <li><a href="#">Link</a></li>

      </ul>
    </div><!-- /.navbar-collapse -->
    </div>
  </nav>

If you're still encountering issues, could you possibly generate a Fiddle with your entire code included?

Make sure you have included the @import 'bootstrap'; statement in your app's asset stylesheet. If not, create a new file named "customization.css.scss" under app/assets/stylesheets and add the @import 'bootstrap'; line to it.
