Expand/collapse icons for sections are missing in WebHelp output

[kkearney2]

Has anyone else had this issue? The carat that lets you expand or collapse section content is not appearing in our WebHelp output.
It used to.
We are now on DITA Open Toolkit bundled with Oxygen 27.1, build 2025041503
Thanks for any ideas!

Hello,

I've tested using <oXygen/> XML Editor 27.1, build 2025063013 and cannot reproduce the issue.
I can see you are using an older build (2025041503), could you try to update to the last one and see if you reproduce the issue?

Regards,
Julien

Yes, will do. Thank you.

Updated to XML Author 28.0, build 2026020208 and I still see the issue. Our customizations may be causing this. I'll continue digging.

Hello,

Please also make sure the 'webhelp.show.expand.collapse.sections' parameter is enabled.

Yes, it is. That was the first thing I checked.

Hello,

You can also try to explore these paths:

• Make sure the sections have a title, the expand/collapse button is anchored to it
• Inspect the title element in the HTML content to see if you have <span class="wh_expand_btn"/>, this is the anchor
• Check the presence of the oxygen-webhelp-icons.ttf font file in the output directory, if it is missing the icons will appear as letters
