# Mass Edit Parameter Options Filterer

This Apex hook is used with the optional **Mass Edit** feature. **Mass Edit** allows a user to use a single action to change selected lines in the **Line Items** list or **Workspace**. A single **Mass Edit** action can require parameters that the user has to enter. A parameter can be of type **Picklist**.

This hook allows the configurator to control the options a user sees in the picklist based on the current context of a deal and that user. For example, the **Picklist** parameter may represent available **Locations** that some users are not allowed to use. In that case, these values can be filtered based on the user ID.

This hook occurs when the parameters of the type **Picklist** are rendered, before the user selects them to see available values.

## Apex hook class

- It must implement the **zpl.MassEditParameterOptionsFilterer** interface.
- It must have a global access modifier.
- You must specify the Apex hook class name in the **Mass Edit Parameter Options Filterer** field of the **Mass Edit Policy Type**.

## Interface definition

global interface MassEditParameterOptionsFilterer
{
    List<PicklistValue> getFilteredOptions(
            UserEnteredParameter__c currentParameter,
            List<PicklistValue> defaultParameterOptions,
            UserEnteredParameter__c[] allParameters,
            Id headerRecordId);
}
```

## Example of class implementation

```
global with sharing class SimpleMassEditParameterOptionsFilterer implements zpl.MassEditParameterOptionsFilterer
{
    global List<PicklistValue> getFilteredOptions(UserEnteredParameter__c currentParameter,
            List<PicklistValue> defaultParameterOptions, UserEnteredParameter__c[] allParameters, Id headerRecordId)
    {
        if (currentParameter.DisplayName__c.equals('Select an option'))
        {
            List<PicklistValue> picklistValues = new List<PicklistValue>();
            picklistValues.add(new PicklistValue('test1', 'test1', false, false));
            picklistValues.add(new PicklistValue('test2', 'test2', false, false));
            return picklistValues;
        }
        else
        {
            return defaultParameterOptions;
        }
    }
}
