Powerful Filters is a multifunctional addon for wpDataTables which widely extends the default filtering functionalities that wpDataTables provides for Tables in WordPress. The addon will add several new features to wpDataTables:

• Cascade Filtering – from left to right (dependent) - with this option users will be able to choose filter values in the order from left to right, options list in each next filter will be narrowed down by previous one; each next filter will become enabled only when a selection in the previous one is made.
• Cascade Filtering – free (independent) - this feature allows to use Cascading Filters in WordPress Tables without the restriction to always define the filter values from left to right. Users can make a selection in any filter, and it will narrow down the filters for all other columns. It is implemented in a similar manner in popular spreadsheet tools (Excel, Google Spreadsheet, etc.)
