INSTRUCTIONS: In order to add a sidebar anchor:

  1. Duplicate the existing item, listed as a 1/6 text field. (Or create a 1/6 column and add a text field, modify the class so it’s exactly “additionalAnchor”).
  2. Modify the text field inside the 1/6 column. Inside there, modify the HYPERLINK so that it would go to a corresponding section with a “#” in front of it. (Example, we have a “chief” section on the page, then it would make sense to have the hyperlink go to “#chief”)
  3. Then change the hyperlink TEXT to a appropriate label.
  4. IMPORTANT: If not done already, go into that CONTAINER that corresponds to your anchor (i.e. Meet The Chiefs), and add an ID matching the anchor’s HYPERLINK WITHOUT the “#”, i.e. “chief”.
  5. (If using side bar widget box, then there’s a saved copy of a widget box COLUMN, grab it in the column library, it should 1/6 of a length of a column.)

NOTE: Order added to the sidebar is from last to first.
