My problem is when i am select deparmentName i want to select change background color for parent tag(orgName) and selected deartmentName.

For Example i am selected in orgName1(orgName) in that i selected Enginnering (department) i want to change backgroundcolor for orgName1 and Engineering and again i selected orgName2 (orgName) and departmentName is ItBhanu i want to apply background color for those two and remove before apply background color.

How can i do this..

If I understand you correctly you are trying to remove some style from previous elements and apply news elements to New Ones.

First of all, create a class which shows elements has selected, something like:

.selected { background: #ddd; }

Then on jQuery you have to attach to the click event of your anchor a tags.

$("a").on('click', function() {
   //Now this is run when all `a` will be clicked

   //First lets remove selected class from previously selected items


   // And lets add selected to currect element and this parent
