Remove / Delete jQuery droppable item

I have a simple drag and drop feature using jQuery,
I have it so that when you add a certain class it will insert a certain input field for that class.
I cannot figure out, however, how to remove an item already dropped?
I just want a nice little x or something next to each element dropped to remove it from the drop box.

Original Script without X button.

$(function() {

$( "#catalog" ).accordion();

$( "#catalog li" ).draggable({

appendTo: "body",

helper: "clone"

});

$( "#cart ol" ).droppable({

activeClass: "ui-state-default",

hoverClass: "ui-state-hover",

accept: ":not(.ui-sortable-helper)",

drop: function( event, ui ) {

$( this ).find( ".placeholder" ).remove();

var el=$("<li>"+ui.draggable.text()+"</li>").appendTo(this);

}

});

</script>

var el=$("<li>"+ui.draggable.text()+"</li> <a href='#'>[x]</a>").filter('a').click(function(){el.remove()}).end().appendTo(this);

}

});

</script>

[Mac OSx86] How To Change Resolution (VMware)(leopard)

Description:
How to increase the resolution of OSx86 in VMware without VMware Tools

*********
There are 2 ways you can do this.

Method 1: Temporary

   When OSX is booting, tap F8 to get to the boot prompt
   Type in "Graphics Mode"="1280x1024x32" (with quotations, replacing the resolution with the resolution you want)

Method 2: Permanent

   Boot OS X
   Open the TextEdit program in the Applications folder
   With TextEdit, open the file: /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
   Open the file, and add these two lines (right after the Yes line if you are on Tiger or line if you are on Leopard)

<key>Graphics Mode</key>
<string>1280x1024x32</string>

   Replace the 1280x1024x32 with the resolution you want
   Then, in go to File >> Save As..
   Save the file as com.apple.Boot.plist on the Desktop (make sure the .plist part is there!)
   Navigate the the /Library/Preferences/SystemConfiguration/ folder
   Drag your com.apple.Boot.plist file on the Desktop into the folder window
   When a messages appears, click Authenticate and Replace and enter your password
   You're done! Reboot OS X to see the changes

Here is an example of what the com.Apple.boot.plist file looks like with Leopard:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://
www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
   <key>kernel</key>
   <string>mach_kernel</string>
   <key>Kernel Flags</key>
   <string></string>
   <key>Graphics Mode</key>
   <string>1280x1024x32</string>
</dict>
</plist>

Note:

sudo -s

Try sudo -s from the Terminal. I'm 100% sure that the password is "pcwiz" in lowercase.
