The interface should be organized in 3 tabs:

• in the first one (selected by default), I can see the section name, identifier and id. This tabs also displays an edit button and a remove button. The user can remove the section (ie the remove button is not disabled), if the section is not assigned to any content or if it is not used in any policy. The user can edit the section (ie the edit button is not disabled) if he has the policy section/edit.
• in the second one, a datatable displays the content assigned to this section and a button labeled "Assign this to a subtree". The user can assign the section to a subtree if he as the policy section/assign for the section.
• the the third tab displays the roles and the policies in this role limited by the section.

The same feature is more or less available in the legacy admin (for instance <url to admin>/section/view/3) or in the AdminBundle.

For now, the datatable should not be implemented as it should reuse the same code as the children list which is not yet ready.
