Hi, if you would like to use Bootstrap’s default behavior (the whole item to act just as sub menu toggle in collapsible mode), you can use the following data-* attribute option:

This is also mentioned at the end of the demo page in the “Quick customization” section:

Please let me know if you still have any questions.
Cheers!
