Go to [Animations](https://matplotlib.org/devdocs/gallery/animation/index.html) from the navigation section on the left hand side.\r\n2. Click on the animation examples either from the side navigation section or from the thumbnails in the main page. \r\n\r\n**Expected Outcome:** Side navigation section continues to show the links of examples gallery\r\n![expected behavior](https://user-images.githubusercontent.com/81802035/236882377-8cc7912b-d0c0-428c-9744-9ebd95f1a6de.png)\r\n\r\n**Actual Outcome:** Side navigation section shows the matplotlib API reference links instead.\r\n \r\n![unexpected behavior](https://user-images.githubusercontent.com/81802035/236882402-21dc4766-5aec-4b65-ab9a-a138ecbc5294.png)\r\n\r\n**Result:** UX is negatively affected, navigation is inconsistent compared to everywhere else in the documentation.\r\n\r\n**Note:** Not reproducible for these examples, breaks for all other animation examples: \r\n- [pyplot animation](https://matplotlib.org/devdocs/gallery/animation/animation_demo.html)\r\n- [Multiple axes animation](https://matplotlib.org/devdocs/gallery/animation/multiple_axes.html)\r\n- [pasuing and resuming an animation](https://matplotlib.org/devdocs/gallery/animation/pause_resume.html)\r\n- [animated scatter saved as gif](https://matplotlib.org/devdocs/gallery/animation/simple_scatter.html)\r\n\r\n\r\n**Possible reasons:** Animation renderer could have something to do with it, but then again, the above 4 examples don't reflect that. Needs root cause analysis.  \r\n\r\n**Reproducible in** Mozilla Firefox, Edge as well as Chrome. Reproducible across devdocs, stable and the older versions.\r\n\r\n**Actionability:** The scope is limited to the Animation examples in the Examples Gallery as far as I have found out. For now, this issue isn't critical or high priority.  \r\n\r\n\r\n### Suggested improvement\r\n\r\nThe section navigation div should contain the toctree of the Examples gallery links, not the API reference links. \r\nFix  should have this result:\r\nUnexpected div: \r\n![unexpected div](https://user-images.githubusercontent.com/81802035/236885741-db45d37a-04e6-493a-a846-6540e1fe85dd.png)\r\nshould be more like the expected div: \r\n![expected div](https://user-images.githubusercontent.com/81802035/236885811-fa09729c-8eb1-4477-9167-a60ce6c8744c.png)\r\n\r\n","author":{"url":"https://github.com/codingtosh","@type":"Person","name":"codingtosh"},"datePublished":"2023-05-08T17:12:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/25836/matplotlib/issues/25836"}
