I came across a requirement while building a site in SharePoint 2007 where I have to display the left menu only to administrator and Thanks to Mark Wagner for his quick and to the point post on SPSecurityTrimmedControl.
What exactly I did was:
1. Open the Default.aspx in SharePoint Designer.
2. Select the left menu and then select Create Custom Content.
3. Arranged the tags as follow:
<asp:content contentplaceholderid="PlaceHolderLeftNavBar" id="Content2" runat="server"> <sharepoint:spsecuritytrimmedcontrol permissionsstring="ManageWeb" runat="server"> All the divs and HTML for the menu goes here. </sharepoint:spsecuritytrimmedcontrol> </asp:content>
Now the menu will only appear for users having administrator rights.
Note: Also, you can directly implement this in Master Page for hiding View All Site Content.
