1.) Drag an HTML widget onto the page
Paste the following code into the widget:
<a href = '#a1'>Anchor 1</a><br/>
the italic text is what the user will see as a link
the bold text is the place in the page where clicking the link will take the user.
2.) Drag an HTML widget onto the page and place the following text into it:
<a name = 'a1'></a>
a1 is the same as the bold part of the link in step 1 (without the #).
3.) Now drag a text widget onto the page and place it below the HTML widget you just added. Place your content in here.
Done. Now you have a table of contents, an anchor on the page to which a link is connected, and a block of text underneath that link for the user to see. Repeat these steps as many times as you like to create more links to blocks of text within the same page.
