Fix Dropdown Arrow Direction for Latest New 2025

[KomatiBhavaniSankar]

Hello @cwhite911, and maintainers,

First, I sincerely apologize for closing the previous PR without consulting you beforehand. That was an oversight on my part. Based on the review comments and suggestions, I have now carefully implemented the requested changes and raised this new PR. I hope this update is closer to the expected standard.

Regarding the “Latest News 2025” dropdown arrow behavior #575 :
I followed the suggested markup-based solution to avoid additional JavaScript. However, after testing, the toggle icon behavior still shows design error and I saw a limitation when relying purely on Bootstrap’s default behavior. From my investigation, this appears to be a Bootstrap constraint, and a minimal JavaScript solution would fully resolve the issue. I wanted to highlight this transparently in case using a small JS snippet is acceptable.
Output Screenshot based on Suggestion:

Important note about the hamburger menu (production issue)

I would also like to explicitly highlight that the hamburger menu is not working in the production site. While investigating this issue, I noticed that the codebase predominantly uses Bootstrap 4, but some components are already written using Bootstrap 5 conventions. This mix causes the hamburger menu to fail in production.

To prevent breaking existing behavior, I initially added the Bootstrap script in
themes/grass/layouts/partials/navigation.html rather than partially modifying markup.
To address this properly and transparently, I opened a separate issue and PR:

• Issue: Bug Report: Hamburger Menu Not Working on Mobile (Production + Development) #573
• PR: Fix issue #573:Hamburger Menu Not Working on Mobile (Production + Development) #574

This PR focuses on resolving the production hamburger menu issue in a cleaner and more consistent way.

Based on the feedback from the earlier PR (#576), I have also:

• Removed unchanged files from the PR
• Removed redundant library imports
• Improved markup indentation and consistency
• Avoided unnecessary JavaScript where possible

Thank you very much for your detailed reviews and guidance. I appreciate your patience and am happy to revise further based on your feedback.

Best regards,
Komati Bhavani Sankar
