how to hide webpart from a group?

can i hide (not by co开发者_开发知识库de) a webpart ONLY from a specific group?

Could you elaborate a bit? what kind of group do you mean? SharePoint security groups? If so, you could try audience targeting.

Be aware though, audience targeting is not the same as real security groups, meaning someone who for instance knows the exact location of a page hidden to him through audiencing, he can just enter the url and he'll see the page.

You have to use conditional formatting . You can create conditions for groups
