I need some assistance with my PowerShell script. Currently I am able to add a drop down menu to my page, but I am trying to add some subfolders to "Support Center". Also if I wanted to add my drop down to multiple $SiteURL, how do I create it to loop for that?

I have pasted my current code below that adds a drop down in one site URL.

Thank you for any assistance!

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
#Add new Link in Top Navigation
Function Add-SPOTopNavigationLink()

    $user = "user"
    $file = "location"
    #Create new credential object and get encrypted password from file 
    $cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $user, (Get-Content $file | ConvertTo-SecureString)
    $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Credentials
    #Get the Top Navigation of the web
    $TopNavigationBar = $Ctx.Web.Navigation.TopNavigationBar
    #Populate New node data
    $NavigationNode = New-Object Microsoft.SharePoint.Client.NavigationNodeCreationInformation 
    $NavigationNode.Title = $Title
    $NavigationNode.Url = $URL
    $NavigationNode.AsLastNode = $true
    #Get the Parent Node
    $ParentNode = $TopNavigationBar | Where-Object {$_.Title -eq $ParentNodeTitle}
    #Add New node to the navigation
    If($ParentNode -eq $null)
        #Check if the Link with Title exists already
        $Node = $TopNavigationBar | Where-Object {$_.Title -eq $Title}
        If($Node -eq $Null)
            #Add Link to Root node of the Navigation
            Write-Host -f Green "New Link '$Title' Added to the Navigation Root!"
            Write-Host -f Yellow "Navigation Link '$Title' Already Exists in Root!"
        #Get the Parent Node
        #Check if the Link with given title exists
        $Node = $ParentNode.Children | Where-Object {$_.Title -eq $Title}
        If($Node -eq $Null)
            #Add Link to Parent Node
            Write-Host -f Green "New Navigation Link '$Title' Added to the Parent '$ParentNodeTitle'!"
            Write-Host -f Yellow "Navigation Link '$Title' Already Exists in Parnet Node '$ParentNodeTitle'!"
#Config Parameters
#Call the function to Add a New Link in Root of the navigation
Add-SPOTopNavigationLink -SiteURL $SiteURL -Title "TESTING - HOME" -URL "https://yahoo.com"
#Call the function to Add a link in "Support Center" node of the navigation
Add-SPOTopNavigationLink -SiteURL $SiteURL -ParentNodeTitle "TESTING - HOME" -Title "Support Center" -URL "https://google.com"

I think for your requirement, you can go with the megamenu and hub site configuration.

What is Megamenu Navigation?

The much-awaited megamenu navigation was recently launched by Microsoft (February & March 2019). It addresses many issues that users have been facing over the last several years in the traditional drop-down navigation approach. One of the major issues of drop-down based navigation is, if the navigation item lists are more, most of the actual content of the site will be hidden or shadowed by the drop-down menu. This is how the user gets frustrated and it leads to poor user adoption to the site. And also in the drop-down-based approach, we cannot have multi-levels of nested items.

For details refer to the below articles:

How to create hub site in SharePoint Online using PnP PowerShell?


You can write the sites in a CSV file and import it using

Import-CSV -Path C:\SiteURLs.csv

And the loop should look like:

Import-Csv "C:\SiteURLs.csv" | Foreach-Object {
    Add-SPOTopNavigationLink -SiteURL $_ -Title "Support Center" -URL "/"
    Add-SPOTopNavigationLink -SiteURL $_ -ParentNodeTitle "Support Center" -Title "Application Support" -URL "/"
