Dynamic Load Content Page

I have a left menu. when i choose a link on menu, cakephp wil redirect to a page but it dont reload the browser and keep state of menu. How can I do it?

Menu 1 (controller:1, action:index)
Menu 2 (controller:2,action:index)
Menu 3 (controller:2,action:index)

Your question is not clear. Do you want to change the content of the page without reloading the page? If yes, check AJAX.

Sorry english is not my mother tongue. but yes, i wanna change the content of the page without reloading the page. I wanna keep the state of menu.

You should use AJAX technology for that. There are thousands of articles / vdeos on what is that and how to use it.
