jquery slide left right animation

1$('#hello').hide('slide', {direction: 'left'}, 1000); requires the jQuery-ui library. See http://www.jqueryui.com

1This should work:
2
3$('#menu').click(function(event) {
4      event.preventDefault(); // because it is an anchor element
5      $('.whole').animate({
6          right: '200px'
7      });
8      $('#slideMenu').toggle();
9});
10But your position property should already be set in CSS or you might not get exactly what you need.

12Working JSFiddle

14To explain: the function takes a JS object of properties, like this:
15
16{
17    right: '200px',
18    somethingElse: 'value',
19    myboolean: true
20}
21you can also assign this to a var and pass it to animate:
22
23var cssProperties = { right: '200px' }
24
25$('#menu').click(function() {
26  $('.whole').animate(cssProperties);
27});
28You can pass other arguements as readable in the documentation.
