Read about collections here: http://symfony.com/doc/current/reference/forms/types/collection.html
$(function() {
$("#tags").collection();
});"#tags" can be replaced by the name of your collection, some examples: "#user_tags", "#order_items"
Advanced use:
$("#collection").collection({
addButton: $('<a href="#" class="add-collection-item">Add</a>'),
deleteButton: $('<a href="#" class="delete-collection-item">Delete</a>'),
deleteButtonPath: null, // where to append the delete button in the new child
addButtonContainer: null, // where should the plugin put the add button
newChildrenContainer: null, // where should it put new children
onAdd: function (child) {
$(child).find('select').select2(); // some random examples
$(child).find('.datetime').datepicker();
},
onDelete: function (child) {
// do something here after deleting a child
},
});
