I have created a menu which is working fine. But on the page load all the menu items are collapsed. A look look on my code

$(document).ready(function() {
  $("#nav > li > a").on("click", function(e) {
    if ($(this).parent().has("ul")) {
      e.preventDefault();
    }

    if (!$(this).hasClass("open")) {
      // hide any open menus and remove all other classes
      $("#nav li ul").slideUp(350);
      $("#nav li a").removeClass("open");

      // open our new menu and add the open class
      $(this).next("ul").slideDown(350);
      $(this).addClass("open");
    } else if ($(this).hasClass("open")) {
      $(this).removeClass("open");
      $(this).next("ul").slideUp(350);
    }
  });
});

/* nav menu styles */

#nav {
  display: block;
  width: 280px;
  margin-left: -40px;
  list-style-type: none;
}
#nav li {} #nav > li > a {
  display: block;
  padding: 8px 7px;

~~Just do this:~~

$(document).ready(function(){
   $("#nav li:first").find('a').trigger('click');
})

UPDATE

DEMO

$(document).ready(function() {
  $("#nav > li > a").on("click", function(e) {
    if ($(this).parent().has("ul")) {
      e.preventDefault();
    }

    if (!$(this).hasClass("open")) {
      // hide any open menus and remove all other classes
      $("#nav li ul").slideUp(350);
      $("#nav li a").removeClass("open");

      // open our new menu and add the open class
      $(this).next("ul").slideDown(350);
      $(this).addClass("open");
    } else if ($(this).hasClass("open")) {
      $(this).removeClass("open");
      $(this).next("ul").slideUp(350);
    }
  });
  $("#nav > li:first > a").trigger('click');
  //Or else you can go with below one too
  //$("#nav li:first").find('a').trigger('click');
});

Just trigger click on the first item. You can use :first Pseudo Class

$(document).ready(function() {
  $("#nav > li > a").on("click", function(e) {
    if ($(this).parent().has("ul")) {
      e.preventDefault();
    }

    if (!$(this).hasClass("open")) {
      // hide any open menus and remove all other classes
      $("#nav li ul").slideUp(350);
      $("#nav li a").removeClass("open");

      // open our new menu and add the open class
      $(this).next("ul").slideDown(350);
      $(this).addClass("open");
    } else if ($(this).hasClass("open")) {
      $(this).removeClass("open");
      $(this).next("ul").slideUp(350);
    }
  });
  $("#nav > li:first > a").trigger('click');
});

One solution is that you can hard code in html to open that menu

add open class to a and style='display:block' to your ul
```
<ul id="nav">
    <li><a class="open" href="#">Animation</a>
      <ul style="display: block;">
        <li><a href="http:/www.google.com/search?q=design+cartoons+animation">Cartoons</a>
        </li>
        <li><a href="http:/www.google.com/search?q=design+comic+strips+inspiration">Comic Strips</a>
        </li>
```
Or

You can add this before your click event
```
 $("nav").find("li:first a").addClass("open");
$("nav").find("li:first ul").show();
```
