Bootstrap Navbar Issue (Mobile)

Hi all,

Hoping you can help! I’ve been coding with Bootstrap and although the desktop edition works well (see image below) the mobile edition works, but refuses to show any of the links. From what I can see it should work, so I think I’m missing something stupid.

Any help is appreciated!


EDIT - Code is as attached - HTML/Related CSS/Related JS


<div class="uc-mobile-menu uc-mobile-menu-effect">
    <button type="button" class="close" aria-hidden="true" data-toggle="offcanvas"
            <ul id="menu">
                <li><a href="index.php">Home</a></li>
                <li><a href="index.php#about">About</a></li>
                <li><a href="tos.php">Terms of Service</a></li>
                <li><a href="product.php">Product A-Z</a></li>
                <li><a href="#contact">Contact</a></li>
                <li><a href="tel:+441384293222"><i class="fa fa-phone"></i> &nbsp;&nbsp;&nbsp; 01384 293 222</a></li>

If you click on the hamburger icon on the top right (the 3 lines), a drop down menu should appear. If not, be sure to double check if you have linked the relevant Java script and Jquery files to your html. Make sure all link correspond with the Boostrap version. Let me know if this helps.

Maybe you could share you html file here?

The menu appears on the double click, but none of the links associated with the list appear - its blank like in the image (I’ve just cut them from the localhost preview - bottom left is pre-click, bottom right is post-click)

I’ve also added the related HTML/JS/CSS coding if that helps :slight_smile:

Thanks again!

Cool, I see you only added the html relative to the navbar. Did you link the css in the head and Javascript and Jquery at the bottom of your body? I’ve had a similar issue and it was because I linked Javascript and Jquery to a different version of Bootstrap which I was using…

That I did - and both are linked to Bootstrap 3.3.6

Using linked URLs for the bootstrap CSS/JS - not sure whether that could be the cause then perhaps?

<link rel="stylesheet" href=""
          integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">

    <script src=""

Hmmm… I’m not too sure then. I am also quite new to this but thought maybe I could help. Hopefully someone else may be able to help you!

No worries - thanks for trying; your help is massively appreciated!! :smiley:

@mylife42, welcome to the forums.
It looks like your missing the .data-target class and the matching id for the collapsible part. Check out this link to w3schools for additional help with collapsible navbars. (Of course you can Google and find lots more including Bootstraps own documentation.)

Hi Roma,

Thanks for that - I’ll add the .data-target and see if that helps :slight_smile:
