Creating anchor links in Siteworks requires you to actually manipulate the HTML code. To do so, go to the page you wish to edit and select the 'Show HTML' item from the Siteworks editor toolbar. There are two parts to creating an anchor link. First, you must create the link. To create this link, find the text which you would like to make a link. Then insert the following around the text you would like to be a link:
<a href="#unique_name">Text you want to be a link</a>
The unique name can be anything you want it to be (in standard ASCII), but should be descriptive. Now you have created the link and step one is complete. The second step is to indicate where you want the link to point to. Find the text on the page which you would like the link to point to and insert the following:
<a name="unique_name"></a>
Use the same unique_name from the above example.
