Hi Friends,
How to create explorer like menu in Html or java script?
eg
+ Game(inside this Cricket and Football)

when click on + sign it become like--

- Game
-Cricket
-Football

Can anybody suggest me, by which command I can do it?


Buy Laptop||External Hard Drive||Portable Hard Drive

There is no such command for it. You have to use Javascript and CSS to give the tree like look and feel. There are lots of readymade scripts available - both free as well as commercial ones.
Just google with something like "explorer tree in javascript"

Here's just a simpe one. You can tweak it according to your requirement. Like you can add "+" and "-" icons before entries and make the interface cleaner ;). What you need to know is HTML ofcourse plus little JavaScript and HTML DOM.

<script type="text/javascript">
function toggle(obj) {
	var x = obj.getElementsByTagName("ul")[0];
	if( x.style.display == "none" )
		x.style.display = "block";
	else
		x.style.display = "none"; 
}	
</script> 
<body>
<div id="menu">
    <div>
       	<span onclick="toggle(this.parentNode);">Heading 1</span>
        <ul>
            <li>One</li>
            <li>Two</li>
        </ul>
    </div>	
    <div>
       	<span onclick="toggle(this.parentNode);">Heading 1</span>
        <ul>
            <li>Three</li>
            <li>Four</li>
        </ul>
    </div>
</div>

Or like parry_kulk said, you can always search google for premade scripts which are far more stable and well tested.
