Acceptance Criteria

• On Special:Block, add a section under the username/IP input box for Type
• The options should be two radio buttons with labels and help description text.
• The top radio button, which should be selected by default' should read Sitewide. When a block is saved with this selected, the block should behave exactly as it does today.
• The second radio button should read Partial. When selected, a TagMultiselectWidget OOUI element should allow for admins to type up to 10 pages from which the user should be blocked from editing.
  • Page blocks can only be set for existing pages.
    • Validation should occur in the input field or via error message when the "block this user" button is pushed — whichever is simpler
  • Pages can be from any namespace, the user must type in the namespace and colon (e.g. Template:Foobar)
• API:Block should be updated to allow a site-wide OR partial block and the partial block configuration (pages for now, namespaces in the future)
• API:Block and Special:Unblock to delete the restrictions (within a transaction).
• Ensure that expired blocks clean up the restrictions.
