Steps to create sub theme and mutilevel dropdown :-

1. Download the Bootstrap theme from the drupal sites here.

2. Create the subtheme using cdn folder (/bootsrap/starterkits/cdn) , Copy the cdn folder and place the same level folder as main bootstarp folder (sites/all/themes/cdn).

Open the template.php file in your theme for editing.

Look for a function called yourthemename_preprocess_page (replace the yourthemename with your theme’s name).

If this function already exists, you will need to add the if statement to the end of the function just before the closing bracket. Otherwise, you’ll need to create a new function to look like this:

##Drush is your friend

I had used Drush previously so I knew it can be a real time saver. For anyone reading this who is not familiar with Drush, it is a command line tool used to manage a Drupal installation and run all kinds of Drupal commands. Such as: run cron, clear caches, make backups, install modules etc. If you do Drupal development and are not using Drush, you really should. It saves you time and makes working with Drupal more enjoyable by not having to click around the Drupal admin interface that much. Drush is your friend.

Copy folder from one location to another by excluding specified folder .

 - rsync -av --progress sourcefolder /destinationfolder --exclude thefoldertoexclude
