#### Vertical Layouts

You can change or customize the left side navigation very easily.

##### How to add new menu items/change menu items?

In order to add, change or remove menu items from the left side navigation, simply edit in file `src/partials/sidebar.html`. The change would reflect in all the html files automatically. We are using `gulp-file-include` which would actually take care of including the `sidebar.html` file content in all the html pages.

##### How to change width?

In order to change the width of left side navigation bar, open a file `src/assets/scss/_variables.scss` and change the value of variable `$sidebar-width`. The default value is set to `260px`.

Each of the layout options is provided below with steps you would need to perform:
