How do I add cascade filters with the Powerful Filters add-on?

How to install the addon?

Installing the Powerful Filters add-on is a quite straightforward process if you have some experience with WordPress plugins. Once you’ve uploaded the plugin using either of the two upload methods, you should see the Powerful Filters add-on in your plugins list.

• Go to your WordPress admin panel, open the “Plugins” page, then click “Add new”, there choose “upload” and then browse to the ZIP file that you’ve downloaded from CodeCanyon.
• Go to our store , login with the credentials you received via e-mail when you purchased the plugin, download the plugin and extract the ZIP file that you’ve downloaded. Once you’ve done that open your WordPress installation through FTP, browse to wp-content/plugins, and upload the extracted folder there.

Once you’ve uploaded the plugin using either of these 2 scenarios, you should see the Powerful Filters addon in your plugins list. Just click “activate”, and you’re good to go!

How to enable cascading with Powerful Filters?

After activating the Powerful Filters add-on you will notice several new options in the Sorting and Filtering tab on the table configuration page.

To try how the cascade works, enable the “Cascade filtering” option and choose either of two available logic types: “From left to right” (dependent filtering), and “Free” (independent filtering).

What is dependent (“From left to right”) filtering?

“Dependent” filtering means that you will only be able to make choices in the filters in order, from left to right. New from version 1.3, there is an available option for dependent filtering called “Hide all filters except first one”.

What is independent (“Free”) filtering?

“Independent” filtering means that there is no filtering order restriction — you can choose values in the filters however you wish.

1. If your table has the option “Filters in a form” enabled, and the filter is rendered outside of the table, Powerful Filters add-on will add two new options to the filtering tab: “Hide Table” and “Search button”.
2. “Hide Table” – this option allows you to hide the table content before some selection is made in the filters. It is a great feature if, for example, you only want to show users data in the table that is based on an input of a particular filter (e.g. only a specific type number, or a single category), without distracting them by showing full table content all the time.
3. Search button will allow you to add or remove the search button. By default, wpDataTables data is filtered automatically when any filter has been changed; and the Search button is enabled. Filtering won’t be applied “on the fly” – the table will only be filtered when you click the Search button next to the filters.
4. Once you enable the Search button, you will see one more option – Disable search button. Enabling this option will keep the search button disabled until a user selects options in all available filters. This is useful when you only need to show users a particular row. In this way, you restrict users from applying broader filters.
