Web Part “Hidden” option is greyed out on team site wiki pages
Question
For all the Web Parts on my SP 2010 team site wiki page, the "Hidden" option is greyed out (under Edit Web Part > Layout).
How can I activate this option?
Solution
I ran into the same issue a while ago. As a temporary workaround I exported the WebPart into a DWP file and edited it with a text editor (I prefer Notepad++). Once done I imported it back and added it to the page.
