Hi Josh

Bound lists is what you're looking for, have a look at this KB How to create a Bound List-box with 4 Levels (4244019)

function GetCurrentValue($Request, [string]$AttributeName)
{   
    trap {continue}
    $value = $Request.Get($AttributeName)
    if($value -eq $null)
    {
        $DirObj.GetInfoEx(@($AttributeName),0) | Out-Null
        $value = $DirObj.Get($AttributeName)
    }
    $value
}

The above script is in essence a scripted "property validation and generation rule" (granted without the validation part).

The arrays within the script $Level1PossibleValues, $Level2PossibleValues, $Level3PossibleValues and $Level4PossibleValues are populated with values as per the value currently set in the higher level, meaning initially the possible values for Param1 is Plants or Animal, but Params 2, 3 & 4 would be - or -

If Param1 is set to Animals, Param2 would have the option for Insects, Fishes, Birds and Mammals, but Params 3 and 4 would be - or -

When Param 1 is Animals, Param2 is Mammals, Param3 would show only predators, and Param4 would be - or -

When predators for Param3, param 4 would offer Wolf, Tiger, Lion or Cat.

However hardcoding in the script is not ideal, you'd be better to have a CSV or some other data source, where you can populate the arrays with the values you want, depending on the previous levels selected item.

That could be a single CSV with 4 columns, where you select the values for each level like

$Data = Import-csv "Somefile"

$level1 = GetCurrentValue $Request 'edsvaLevel1'
$level2 = GetCurrentValue $Request 'edsvaLevel2'
$level3 = GetCurrentValue $Request 'edsvaLevel3'
$level4 = GetCurrentValue $Request 'edsvaLevel4'

$Level1PossibleValues = $Data | Select-Object Level1 -unique
$Level2PossibleValues = $Data.where({(($_.Level1 -eq $Level1) -and ($_.Level2 -eq $Level2))}) | Select-Object Level2 -unique
$Level3PossibleValues = $Data.where({(($_.Level1 -eq $Level1) -and ($_.Level2 -eq $Level2) -and ($_.Level3 -eq $Level3))}) | Select-Object Level3 -unique
$Level4PossibleValues = $Data.where({(($_.Level1 -eq $Level1) -and ($_.Level2 -eq $Level2) -and ($_.Level3 -eq $Level3) -and ($_.Level4 -eq $Level4))}) | Select-Object Level4 -unique

Hope that helps

Thanks Stu, appreciate the quick response. I will test this out and reply back in a bit.
