# Post-Processable Filter Picklist Configurer

Use this Apex hook to control which options are shown in the **Line Items Post-Processable Filter Field**.

This hook occurs when available options for a given **Line Items Post-Processable Filter Field** are determined prior to a user opening that field and selecting one of those options.

## Apex hook class

- It must implement the **zpl.PostProcessableFilterPicklistConfigurer** interface.
- You must specify the Apex hook class name in the **Picklist Configurer Class Name** field of the **Post-Processable Filter Field**. Make sure you have included your Salesforce org namespace prefix in the Apex class name.

## Interface definition

```
/**
 * A hook that provides a full control to the content of the picklist options for the PostProcessableFilterField control.
 */
global interface PostProcessableFilterPicklistConfigurer
{
    /**
     * @param picklistValues the picklist options returned by querying the associated SObject
     * @param config the filter configuration
     *
     * @return the options to display in picklist
     */
    List<zpl.PicklistValue> getPicklistValues(List<zpl.PicklistValue> picklistValues, zpl__PostProcessableFilterField__c config);
}
```

## Example: class implementation

```
global with sharing class SamplePostProcessableFilterConfigurer implements zpl.PostProcessableFilterPicklistConfigurer
{
    global List<zpl.PicklistValue> getPicklistValues(List<zpl.PicklistValue> picklistValues, zpl__PostProcessableFilterField__c config)
    {
        picklistValues.get(0).label = 'All Products';
        return picklistValues;
    }
}
```
