# Step 5: Close window
window.close()

Hi Can you demonstrate how to create a table which could be used to enter data - parent/child relation ship. For example I want to create a new class and add 2 or more students to the class along with other informations, say assigned group name etc. I should be able to select student name from a drop down in the table.
