PowerShell Script Not Working As Intended When Getting AD Groups - powershell

Question

I am working on a PowerShell script with a menu to select different ways to search info in Active Directory. The command with Get-ADUser works correctly, but the command with Get-ADPrincipalGroupMembership has an odd behavior. When I select that option (3) and enter a username and run the command nothing gets output to the display, if I then quit by using (Q) on the menu the groups then display.
function Show-Menu
{
param (
[string]$Title = 'AD Search Tool'
)
cls
Write-Host "================ $Title ================"
Write-Host "1: Search Users by Title"
Write-Host "2: Press '2' for this option."
Write-Host "3: List User's Groups"
Write-Host "Q: Press 'Q' to quit."
}
do
{
Show-Menu
$input = Read-Host "Please make a selection"
switch ($input)
{
'1' {
cls
$title = Read-Host -Prompt 'Enter Title'
if ($title){
Get-ADUser -Properties SamAccountName, Enabled, Title, EmployeeID -Filter "(Title -eq '$title') -and (Enabled -eq 'True')" | select Enabled, EmployeeID, Name, SamAccountName, Title
}
} '2' {
cls
'You chose option #2'
} '3' {
cls
$user = Read-Host -Prompt 'Enter User Name'
if ($user){
Get-ADPrincipalGroupMembership $user | select name | sort name
}
} 'q' {
cls
return
}
}
pause
}
until ($input -eq 'q')

Answer 1

Just use Write-Host to write the result immediately.
To do it through the pipe, you can use Out-String first.
Therefore
Get-ADPrincipalGroupMembership $user | select name | sort name | Out-String | Write-Host -ForegroundColor Cyan
instead of
Get-ADPrincipalGroupMembership $user | select name | sort name
will do the trick.
* Color is optional. I just like cyan.
