I need to have 4 levels of selects which will be dependant on the higher level. For example, I select a site value, which then needs to populate the block select with the available blocks for that site. When I select the block, I need the third select to be populated with the levels available for the selected block within the site. How can I do this using AJAX to refresh the select lists?
