I'm able to create multi level control under tfs template on team explorer using WitCustomControlSetup2012.msi provided by code plex.
However I'm not able to do it for web access, i can see options but those are not in proper shape may be css issue. Also I'm not able to install WitCustomControls.MultiValueControl.zip as i don't see Control Panel -> Extensions tab (http:\server:8080\tfs\admin\extensions)
when i access web tfs.
Can you please help me to get that control planel enabled on my team web access. I think i have missed some installation. When I navigate to http:\server:8080\tfs\admin\extensions it thows 404 error.
