Step 1. You will write an html web page called editItem.html (or editItem.py), which links to an external Javascript file named ActionOnItem.js. The contents of editItem.html (or editItem.py) should include dropdownlist1, dropdownlist2 and a button. First Add items to the dropdown list using HTML code. Secondly, click the button MoveHere. You can add other form elements if you think are needed to complete this program with more relevant information.

Step 2. You will write a .js file named ActionOnItem.js. In ActionOnItem.js file, you should write a function called moveItem( ) which receive itemName parameter and remove that item from dropdownlist1 and add that item to dropdownlist2.

Step 3: when MoveHere button is pressed and display result on your HTML page.

Step 4. Extend your programs by creating a new function called countItem() in ActionOnItem.js that calculates and displays number of items on both dropdownlist1 and dropdownlist2. You can add another button on the editItem.html to call this function.

Step 5. You should display appropriate error messages if noitems in dropdownlist1 to remove.

Step 6. Demonstrate that your program runs on different web browsers e.g. Edge, Firefox and Chrome (attach screenshots).
