It is possible to create links within a banner that point to specific piece of content on a page using anchor links. Anchor links work just like hyperlinks between pages on your site, except that instead of pointing to a different page, they point from one place on a page to another location on the same page.
See the Knowledge Base article on anchor links to learn how to add link targets to page content.
The link to the anchors placed in the content will be located on the banner.
To create a link to a named anchor, you will first need to create a banner which will house the link(s). It is best to clone an existing banner; this can be done from Site Manager > Page Banners by finding the banner you wish to use and clicking the 'Clone Banner' link at the top of the page. A new banner will open up automatically, with identical settings to the banner which was just cloned. Give the new banner a name and save it.
Find or create the "Element Type: Text" box within the banner that will display the links. Write your link text in the content area. Highlight the link text, and click the 'Link' button below the text area. The Add/Insert Link window will appear. The anchors in the page text will NOT be populated in the "Anchors" dropdown menu. Instead, write the designator you selected for your anchor link in the "Link URL" field, preceded by the # symbol.
This process can be repeated in order to add multiple links to the banner.
