MultiLookup needs a controller or urls to be specified, by default convention it
will look for a controller with the same name as it + "MultiLookupController"
-
action GetItems - used to show the value in the readonly field, it
will receive a v parameter which is going to be the keys of the selected
items
-
action Search - gets data for the search result in it's popup, it receives
a selected parameter that represents the selected values, it should
return a Json(AjaxListResult), so it has same features as the AjaxList
(table layout, custom item template)
action Selected - gets data for the selected items in the popup
