Open the frame you want to link to a topic, and select the text you want to use as the link.
Click Insert
Hyperlink . The Hyperlink
dialog opens.
In Link to, you can enter the location of the topic you want to link to the frame, or you can select the topic or URL from Select Destination (File or URL), and it automatically appears in the Link to field.
In Frame, select the destination for the link. The selection you make here will determine how the destination topic is displayed on the user's system. You can choose from blank, self, parent, top or any frames in your project.
Click Save
, then preview the frame and check the link.
Note: For the topic to open in the frame, the frameset must be open in the HTML Help viewer before the user clicks the link. For example, a page in the TOC displays a topic in the left-hand frame. Links in this topic display the destination topics in the right-hand frame.
