prevent mmenu close on click on page - mmenu

Question

I have one mmenu instance. The default behaviour is that it closes when I click outside of the menu. How can I prevent this behaviour? To force the menu closure I want to use only a predisposed button (already working)
------------------ ADD Some details --------
My mmenu instance is as below
<nav id="listPanel">
<ul>
<li id="closeButtonLi"><span id="panelButtonClose" class="glyphicon glyphicon-chevron-right"> Chiudi</span></li>
<!--<li style="padding:10px"><input type="text" class="form-control" placeholder="Aggiungi atleta"></li>-->
<li id="athSelectorLi" style="padding:10px">
<input id="athSelector" style="width:70%;"/>
<img id="plusButton" style="width:35px;height:auto;cursor:pointer;margin-left:12px;" src="../../../docsUI/images/common/add.png"/>
<img id="removeButton" style="width:35px;height:auto;cursor:pointer;margin-left:7px;" src="../../../docsUI/images/common/remove.png"/>
</li>
<li >
<table id="athTable" class="hover compact" width="95%" cellspacing="0">
<thead>
<tr>
<th>markerColor</th>
<th>bib</th>
<th>name</th>
<th>avgSpeed</th>
<th>locate</th>
<th>remove</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
</li>
</ul>
</nav>
$(document).ready(function() {
$("#listPanel").mmenu({
"classes": "mm-light",
"offCanvas": {
"zposition": "front",
"position": "right"
}
}
});
$("#panelButton").click(function() {
$("#listPanel").trigger("open.mm");
});
$("#panelButtonClose").click(function() {
$("#listPanel").trigger("close.mm");
});
});
What I need is to close the #listPanel menu only using the close button
<li id="closeButtonLi"><span id="panelButtonClose" class="glyphicon glyphicon-chevron-right"> Chiudi</span></li>
With current implementation, the button works as expected, but the menu closes also when I click outside the menu in the remaining part of the page. I want to avoid exactly it (close the menu clicking on the page as is the default behaviour as described in http://mmenu.frebsite.nl/tutorial/open-and-close-the-menu.html)
I searched both on Stack Overflow current answers and on website documentation, but I did not find any solution. The only API present is the onClick but it is not relevant for my needs.

Answer 1

$('#mm-blocker').unbind('mousedown')

Answer 2

This will remove div which will prevent close mmenu
$('#mm-blocker').remove();
better than unbind mousedown
