Bootstrap Collapsed Menu Links Not Working on Mobile Devices

Looks like this is a known issue with Bootstrap (https://github.com/twitter/bootstrap/issues/4550 and possibly also https://github.com/twitter/bootstrap/issues/7968) which is very disappointing because it's been open for a long time and never fixed, and the primary reason to use Bootsrtap is its promise of responsive design.

The fix proposed at https://github.com/Bitergia/bootstrap/commit/25e8eeb47f01aceed57cb2715036a69395892fa8 seems to work, but it is using the Bootstrap source code, so if you are using the minified version and are not using the source scripts it looks differently.

I fixed it in my case in the minified version by adding the substring "disable-" to the touchstart test, therefore disabling this functionality.

To do that in your minified bootstrap.min.js file, find the substring

"ontouchstart"

and replace it with

"disable-ontouchstart"

Thank you @Shmalzy for trying to help.

I encountered this issue on iPad. I found I was missing the following on the anchor tags:

 href="#collapseSection"

Where #collapseSection is the ID of the collapsing panel. Example:

<div class="panel panel-default">
  <div class="panel-heading"><a class="accordion-toggle" href="#collapseHelp" data-toggle="collapse" data-target="#collapseHelp" data-parent="#accordion">Printing Problems?</a></div>
  <div id="collapseHelp" class="panel-collapse collapse">
    <div class="panel-body">Before you contact the helpdesk, have a look at <a href="Help.asp?PrintHelp">our help system</a>.</div>
  </div>
</div>

You should not need to alter the minified JavaScript to correct this issue, as it works fine in the Bootstrap examples. It's all a matter of formatting your HTML correctly.
