im a begginer in web development.. and i just wanted to know if a list/menu box when clicked/or its items are choose it can cause a trigger to other parts of the site..

ex.

if im going to choose from a list/menu with names listed coming from a mysql db..

it will trigger the next list/menu to only list the related information of the name chosen from a mysql db???
can i have a sample code???I dont like reading sites, i can read English but im having hard time understanding it. :(
 
You can create an ajax handler to monitor the value of the listbox after the user selects a new value and poll your server side script and repopulate your page with new data based on what the user selected. jQuery makes this process relatively painless:

or
