I am displaying details of items in a collapsible block. I thought it would be nice to use input boxes so the item could be edited and updated right there. I added a button in the collapsible block and have it invoking a service when clicked. I do the mapping from the data in the collapsible block before send but it doesn't get any info. I guess that makes sense that it doesn't know what data from the collapsible list to get, but how do I map the data appropriately when they click update? Do I need to use javascript?
