This post will be about how to make a simple website that supports multiple modules which are displayed in a single page. By default unlike a lot of other javascript frameworks, knockout.js doesn't really support modules. But fortunately we can implement this functionality using knockout.js itself.

On the left of the tab header bar we will have a menu from which we can select a module to open just by clicking on it. Once we open a module, a tab header will appear up in the tab header bar with the name of the module. And down in the tab content pane, the content of the current tab will appear.
