drupal views restore issue

I had a view which had a number of displays. I clicked on "Remove display" one of them and saved the changes. Now when i go to that display, the "Fields" area is greyed out. How can i 开发者_运维技巧restore the display back to original ?

I'm guessing here, but once you click save for the view, and then return to the view it'll go away.

If you choose a display then click "Remove Display" and save the changes to the view, you should no longer see it in the list of displays for that view (hence removing the display).

After clicking "Remove Display," you can only restore the display before saving the whole view.
