Make a block display in one page and not in other I am using Drupal 7 with omega and adminimal theme. I use adminimal theme for my iframe in the site (using entity iframe module). I would like to display a block in the adminimal theme alone, but not in my omega theme.

I used the default block settings, "Only the listed pages", but this display the block in both the themes.

So is there a way to configure the display options per theme?

Any help would be widely appreciated.
In the block's Region settings you can specify the block to be displayed in which region of respective themes(Admin and site theme) as below:
