Add a horizontal rule tag to the Basic HTML text format, and a corresponding button to its editor configuration.

Site prerequisites

  • The Basic HTML text format must exist. This is created on your site when you install with the core Standard installation profile.

  1. In the Manage administrative menu, navigate to Configuration > Content authoring > Text formats and editors (admin/config/content/formats). The Text formats and editors page appears. Note that the names of the text formats that came with your installation profile are shown in English on this page; see Section 2.7, “Concept: User Interface, Configuration, and Content translation” for an explanation.
  2. Click Configure for the Basic HTML text format. The Basic HTML page appears.
  3. Note that CKEditor is selected in the Text editor field. This allows you to configure the editor’s toolbar.
  4. Drag the horizontal line button from Available buttons to the Active toolbar. Toolbar items can be visually grouped together using a vertical divider. As an alternative to dragging, you can tab to select buttons and then move them using keyboard arrow keys.
