In HubSpot Anchor Links are setup in two steps. First, the anchor link has to be defined (where it goes); then the anchor link has to be linked (where the link is).
Anchor Links in POWER
All POWER modules have an Anchor Link ID that you can define.
The ID must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".")
You can separate multiple words in an anchor with hyphens, it is best to keep it short and clear.
Because the ID will be used in your URL it is recommended to be lowercase.
Once you have defined the Anchor Link ID, you can use this ID to create a URL that can be used in many ways.
Anchor Link ID => test
Link to External => #test
EXAMPLE: If your anchor link is defined as features you can setup links to this location on the page one of two ways:
1. On the same page, you can use the relative URL by adding #features as an "External" link.
2. On other pages of your website (or externally) you can use the full page URL with the anchor link at the end:
Rich Text Anchor Links
For sections or modules with content using rich text editors, you can also setup anchor links within the text.
This is especially helpful for long form content and blogs.
HubSpot Knowledge-Base:→ Insert and Manage Anchor Links
HubSpot allows you to select the defined anchor links via Anchor on this page.
The list of anchor links will only show the ones you configured within the rich-text fields of that page.
This list does not analyze and show all available anchor links, including those setup within the module settings using Anchor Link ID.
You can insert this as Link to "URL" and simply add a # before the id you chose.
