About Customizing Publication Sites
In addition to customizing the Pro/WEB PUBLISH output through configuration options, the Web administrator can customize your publication sites by editing the index.html file in the publication directory so as to change some of the frame names or add more frames with a specific name. Once the index.html file is tailored to your company requirements, the Web administrator can use that customized index.html file to set up other publication sites.
You can customize the following aspects of the publication:
Select formats to use for model representation
Add an additional frame to include the model tree inside the Web page
Add additional frames, including step-specific frames
Do not remove the PRO_WEB_PANEL frame from the index.html file. Without that frame you cannot load the publication into the Web browser.
