On using Google I found that they are using onclick events in anchor tags.
In more option in google header part, it looks like normal a tag, but onclicking it doesn't get redirected but opened a menu. Normally when using
<a href='more.php' onclick='show_more_menu()'>More >>></a>
It usually goes to 'more.php' without firing show_more_menu(), but I have show a menu in that page itself. How to do like google?

If your onclick function returns false the default browser behaviour is cancelled. As such:
<a href=' onclick='return check()'>check</a>
<script type='text/javascript'>
function check()
{
return false;
}
</script>
Either way, whether google does it or not isn't of much importance. It's cleaner to bind your onclick functions within javascript - this way you separate your HTML from other code.
You can even try below option:
<a href="javascript:show_more_menu();">More >>></a>
From what I understand you do not want to redirect when the link is clicked. You can do :
<a href='javascript:;' onclick='show_more_menu();'>More ></a>
Use following code to show menu instead go to href addres
function show_more_menu(e) {
if( !confirm(`Go to ${e.target.href} ?`) ) e.preventDefault();
}<a href='more.php' onclick="show_more_menu(event)"> More >>> </a>
