Panels to do a specific layout for one content type edit mode How can i use panels to do a specific layout for a content type only for the add and edit form ?
I'm a newbie on panels but not on Drupal.I'm using panels 3 on D7.
will be great to give me examples or tutos ..

Page manager (which, technically isn't the same thing as Panels), manages the url node/% differently from node/%/edit.

When you to go Pages, you need to enable the node edit task, and make configuration to that page, not the node view one.
