If I was to use this accordion example (pasted below) - .0/ponents/collapse/ and place it in a file named test-bootstrap.html how would I format a URL to open the accordion? I am happy to modify the HTML file if I can get the results I need.

I appreciate that there are answers to this question on Stack Overflow but these refer to older versions of Bootstrap or involves clicking on links.

The CMS I am using can construct a URL similar to these -

file:///C:/Users/dvb/Desktop/test-bootstrap.html#collapseOne or

file:///C:/Users/dvb/Desktop/test-bootstrap.html#1

Reset to default 5

This is a really basic example.

If you append ?collapseExample to your URL where collapseExample is the ID of the collapse div you want to show, and then add the Javascript AFTER the HTML code, it will add the show class to the div onload.

You can tidy up the Javascript if you want to break the appended strings down into variables and values.

if (window.location.search == '?collapseExample') {
  $('#collapseExample').addClass('show');
}

Thanks to Daniel's answer above and Stuart's response here Open bootstrap 3 accordion panel from another page I have been able to get things running more or less the way I wanted.

Unfortunately I have had to move the identifier (shown as a simple number here) from the ID to the class. I amended the code to that below.

My simple URL file:///C:/Users/dvb/Desktop/test-bootstrap.html#1 (or #2, #3 etc)
