Answer 1

use

$(function(){
    $('.smallmenuContainer a').click(function(){
         $('.smallmenuContainer a').removeClass('active');
         $(this).addClass('active');
   });
});

it will remove active class from all other a tags and add class to current a

Answer 2

you can use removeClass and AddClass of jquery like this

$('.smallmenuContainer li>a').on('click',function(){
$('.smallmenuContainer li>a').removeClass('active');
$(this).addClass('active');
return false;
});

Answer 3

i dont quite understand what your mean but i think this can help you :

$('.smallmenuContainer').click(function(
//you should put the class you want to assigne here instead of cssclass
$('#smallmenuContainer li>a').removeClass('cssclass');
$(this).addClass('cssclass');
));

Answer 4

$( ".smallmenuContainer a" ).click(function() {
  $( this ).toggleClass( "active" );
});

Don't forget to add the css for the 'active' class.
