Answer 3

Erick Ventura this is not what I want. I want to toggle one of the item which should close other child items also.

Answer 4

$(window).on("load", function(){

$('.save-button').on('click', save_onclick);
$('.cancel-button').on('click', cancel_onclick);
$('.edit-button').on('click', edit_onclick);

$('.save-button, .cancel-button').hide();
});

function edit_onclick(){
setFormMode($(this).closest("form"), 'edit');
}

function cancel_onclick(){
setFormMode($(this).closest("form"), 'view');

//TODO: Undo input changes?
}

function save_onclick(){
setFormMode($(this).closest("form"), 'view');
