I created Table of Contents webpart to just display the Sub Sites, but it is showing the lists (Library, Lists, Discussions, etc...). How can I just show the sub-sites and sub-sub-sites using a web part? I am on SharePoint 2010 Standard.
There is one built in: SharePoint 2010 > Edit > Insert > Web Part > Content Rollup > Table of Contents.
Will that solve your problem?
