If you want to “promote” one of the others to show up first, just move them around in your SSL recipe
Not sure what you mean by "promote". I am not looking to change the default navigation pane as I want the TOC to display on generic opening. This question is related to calling the WebHelp based on the menu option in the application and allowing the navigation pane to open at TOC or Index or Search based on the selection of either Contents, Index or Search menu options available from the desktop application Help menu.
Is this how we call help from an application and open in a specific navigation view?
If you didn’t want to change the default order or appearance of the ToC/Search/Index/Glossary, then yes, you will need to go “under the hood” & tinker with the code that’s your developers use to call the CSH.
