Multi Column Sorting
With PrimeFaces PRO, it’s easy to support, tune and add features to PrimeFaces as if it were an in-house framework. Here is another recent example;
Upon request of a PrimeFaces PRO user, we have added Multi Column Sorting. If metakey like ctrl or command is pressed while a column header is clicked, data is sorted according to multiple order. Dynamic Columns are also supported as well with or without LazyDataModel.
Online Demo is available at PrimeFaces Labs.
