Content Collapsible jquery mobile - jquery-mobile

Question

I have a problem with jQuery Mobile 1.1.0 accordion ( http://jquerymobile.com/test/docs/content/content-collapsible.html )
I have a page with more accordion, and when I press to open / close the section brings me back to the top of the page.
I have already set:
ajaxEnabled: false;
hashListeningEnabled: false;
linkBindingEnabled: false;
this is my code:
<!-- anagrafica -->
<div data-role="collapsible" data-collapsed="true" data-theme="b" data-content-theme="c">

It is not very clear as to what exactly the interface is supposed to look like. However, please look at the documentation: http://jquerymobile.com/demos/1.1.0/docs/content/content-collapsible-set.html
The link you pasted is for a test demo, but the syntax seem to have changed since then.
