Utilizing Bootstrap for creating collapsible elements has been my current approach. Additionally, I've integrated a range selector CDN into the mix. It's possible that some styles from the Bootstrap CSS, particularly those related to collapse elements, are causing issues in the UI.
Interestingly, when the range selector is positioned outside of the collapse element, everything appears and functions flawlessly.

The issue arises when attempting to place the range selector inside the collapse element, resulting in the slider being pushed off-screen.

Troubleshooting the exact root cause of this behavior has proven to be challenging.
