Bootstrap left sidebar toggle menu

Question

I got a script for Bootstrap sidebar toggle menu. It works fine for my needs.

Right now the menu is toggling using Toggle Menu button, that is fine.But I need to close the menu if I click, out side of it.

Please check this Fiddle

and help me out. Thanks.

$("#menu-toggle").click(function(e) {
     e.preventDefault();
     $("#wrapper").toggleClass("toggled");
});

Add a window event to check where you are clicking,

Here is a snnipet :

$("#menu-toggle").click(function(e) {
   e.preventDefault();
   $("#wrapper").toggleClass("toggled");
});

$(window).click(function(e) {
   e.preventDefault();
   if(e.target.id =="menu-toggle") return;
               
   if($(e.target).closest('#sidebar-wrapper').length==0){
        // small device toogled class added auto so remove it
        if($("#wrapper").width() < 768 )
           $("#wrapper").removeClass("toggled");
        else
           $("#wrapper").addClass("toggled");
   }  
});

To get this you have to play with jquery functions like .hasClass, .trigger, .is etc. What i did is, i checked the classes on click and then according to them i wrote this code. Please check

See demo

In detail : First i check the class which is toggling on click of a href so i made a condition that if #wrapperhas toggled class then we will trigger the click event on #menu-toggle but also we have to careful that click should be on body but not the a href of side bar menu that's why i have added another condition with !tag. Hope you will understand and if not then let me know.
