In this tutorial, we will explore how to use the Cascade Filter for wpDataTables to create a powerful and user-friendly filtering system for your WordPress tables.

What is Cascade Filter?

The Cascade Filter is a feature in wpDataTables that allows you to create a hierarchical filtering system for your tables. It allows you to filter your table data based on multiple conditions, with each condition being dependent on the previous one. For example, you can create a filter that first filters by country, and then filters by city within that country.

Why use Cascade Filter?

Using the Cascade Filter can greatly enhance the user experience of your WordPress website. It allows users to quickly and easily filter down large datasets to find specific information. This can be especially useful for complex tables with many columns and rows.

Step-by-Step Tutorial: How to Use Cascade Filter for WordPress Tables

In this tutorial, we will create a simple example of how to use the Cascade Filter for wpDataTables. We will create a table with data about countries and cities, and then use the Cascade Filter to create a hierarchical filtering system.

Step 1: Create a wpDataTable

First, you need to create a wpDataTable with the data you want to filter. To do this, go to the WordPress dashboard and click on "wpDataTables" > "Create a new table". Fill in the table name, add your table columns, and upload your data.

Step 2: Configure the Cascade Filter

Once you have created your wpDataTable, go to the "Settings" tab and click on "Cascade Filter". In the Cascade Filter settings, you can configure the filter to your liking.

• Filter Type: Choose the type of filter you want to use. In this example, we will use the "Hierarchical" filter type.
• Parent Column: Choose the column that will be used as the parent column for the filter. In this example, we will use the "Country" column.
• Child Column: Choose the column that will be used as the child column for the filter. In this example, we will use the "City" column.
• Cascade Filter Order: Choose the order in which the filter will cascade. In this example, we will choose "By Parent" to filter the child column based on the parent column.

Step 3: Add Filters to the Table

Once you have configured the Cascade Filter, you can add filters to the table. To do this, go to the "Table Settings" tab and click on "Add Filter". In the Add Filter dialog box, choose the filter type you want to use, and then select the parent and child columns you want to use for the filter.

Step 4: Customize the Filter

You can customize the filter to your liking by adding a title, description, and icons. You can also choose to show or hide the filter based on user permissions.

Step 5: Test the Filter

Once you have added and customized the filter, you can test it by clicking on the filter button in the table. You should see the filter cascading down to the child column, allowing you to filter the data based on the parent and child columns.
