## More Information

The `wpforms_dynamic_choice_post_type_args` filter provides a list of supported arguments from the post such as Category. Similarly, you can also use the `wpforms_dynamic_choice_taxonomy_args` to pull arguments from the taxonomy of **Tags**.

In this example shown below, the function will process on form ID `789` for field ID `10` and only include posts from the category `11`.

## Examples

```

/**
 * Limit posts or pages displayed by category.
 *
 * @link https://wpforms.com/developers/wpforms_dynamic_choice_post_type_args
 *
 * @param array $args       Arguments from post submission.     
 * @param array $field      Sanitized field data. 
 * @param int   $form_id    Form ID
 *
 * @return $args
 */

function wpf_dev_dynamic_choices_categories( $args, $field, $form_id ) {
    
     // Only on form #789 and field #10
     if ( $form_data[ 'id' ] == 789 && $field[ 'id' ] == 10 ) {

         $args[ 'category' ] = '11';		 
    
     }
	
     return $args;
}

add_filter( 'wpforms_dynamic_choice_post_type_args', 'wpf_dev_dynamic_choices_categories', 10, 3 );
```

## FAQ

#### Q: How can I show only the child categories?

**A:** To display child categories in your form, you need to include both the parent category ID and the child category IDs. This is because the current functionality requires that the parent category is specified to correctly fetch and display its child categories.

```

/**
 * Limit posts or pages displayed by category.
 *
 * @link https://wpforms.com/developers/wpforms_dynamic_choice_post_type_args
 *
 * @param array $args   Arguments for post submission.     
 * @param array $field  Sanitized field data. 
 * @param int   $form_id Form ID
 *
 * @return array Updated arguments
 */

function wpf_dev_dynamic_choices_include( $args, $field, $form_id ) {
    // Ensure form ID is correctly handled
    if ( is_array( $form_id ) ) {
        $form_id = $form_id[ 'id' ];
    }

    // Apply only to specific form and field IDs
    if ( $form_id == 122 && $field[ 'id' ] == 11 ) {
        // Include category IDs - 87 is the parent; 88 and 89 are child categories
        $args['include'] = '87,88,89';
    }

    return $args;
}
add_filter( 'wpforms_dynamic_choice_taxonomy_args', 'wpf_dev_dynamic_choices_include', 10, 3 );

```

This snippet ensures that both the parent category **(ID 87)** and its child categories **(IDs 88 and 89)** are included in the dynamic choices.
