sticky: false

}, options);

return this.each(function() {

cssmenu.find('li ul').parent().addClass('has-sub');

if (settings.format != 'select') {

cssmenu.prepend('<div id="menu-button">' + settings.title + '</div>');

$(this).find("#menu-button").on('click', function(){

$(this).toggleClass('menu-opened');

var mainmenu = $(this).next('ul');

if (mainmenu.hasClass('open')) {

mainmenu.hide().removeClass('open');

}

else {

mainmenu.show().addClass('open');

if (settings.format === "dropdown") {

mainmenu.find('ul').show();

}

}

});

multiTg = function() {

cssmenu.find(".has-sub").prepend('<span class="submenu-button"></span>');

cssmenu.find('.submenu-button').on('click', function() {

$(this).toggleClass('submenu-opened');

if ($(this).siblings('ul').hasClass('open')) {

$(this).siblings('ul').removeClass('open').hide();

}

else {

$(this).siblings('ul').addClass('open').show();

}

});

};

if (settings.format === 'multitoggle') multiTg();

else cssmenu.addClass('dropdown');

}

else if (settings.format === 'select')

{

cssmenu.append('<select style="width: 100%"/>').addClass('select-list');

var selectList = cssmenu.find('select');

selectList.append('<option>' + settings.title + '</option>', {

"selected": "selected",

"value": ""});

cssmenu.find('a').each(function() {

var element = $(this), indentation = "";

for (i = 1; i < element.parents('ul').length; i++)

{

indentation += '-';

}

selectList.append('<option value="' + $(this).attr('href') + '">' + indentation + element.text() + '</option');

});

selectList.on('change', function() {

window.location = $(this).find("option:selected").val();

});

}

if (settings.sticky === true) cssmenu.css('position', 'fixed');

resizeFix = function() {

if ($(window).width() > settings.breakpoint) {

cssmenu.find('ul').show();

cssmenu.removeClass('small-screen');

if (settings.format === 'select') {

cssmenu.find('select').hide();

}

else {

cssmenu.find("#menu-button").removeClass("menu-opened");

}

}

if ($(window).width() <= settings.breakpoint && !cssmenu.hasClass("small-screen")) {

cssmenu.find('ul').hide().removeClass('open');

cssmenu.addClass('small-screen');

if (settings.format === 'select') {

cssmenu.find('select').show();

}

}

};

resizeFix();

return $(window).on('resize', resizeFix);

});

};

})(jQuery);

(function($){

$(document).ready(function(){

$(window).load(function() {

$("#cssmenu").menumaker({

title: "Menu",

format: "dropdown"

});

$('#cssmenu').prepend("<div id='menu-indicator'></div>");

var foundActive = false, activeElement, indicatorPosition, indicator = $('#cssmenu #menu-indicator'), defaultPosition;

$("#cssmenu > ul > li").each(function() {

if ($(this).hasClass('active')) {

activeElement = $(this);

foundActive = true;

}

});

if (foundActive === false) {

activeElement = $("#cssmenu > ul > li").first();

}

defaultPosition = indicatorPosition = activeElement.position().left + activeElement.width()/2 - 5;

console.log(activeElement);

console.log(activeElement.position().left);

console.log(activeElement.width());

indicator.css("left", indicatorPosition);

$("#cssmenu > ul > li").hover(function() {

activeElement = $(this);

indicatorPosition = activeElement.position().left + activeElement.width()/2 - 5;

indicator.css("left", indicatorPosition);

},

function() {

indicator.css("left", defaultPosition);

});

});

});

})(jQuery);
