My dilemma involves a flex container (A) containing two or more flex items stacked in a column. The top flex item (B) is a Bootstrap Collapse panel, while the bottom item (C) consists of two horizontal divs (D and E). The problem arises when the collapse panel (B) expands, causing the bottom item (C) to extend beyond the boundaries of container A instead of shrinking to fit within it. I attempted to rectify this by incorporating 'overflow-y:scroll;' for D and E if needed, but encountered an issue with an unnecessary scroll bar appearing on the right side of C.
Illustrated below:
+------------------------+
| A: Flex Container |
| +--------------------+ |
| | B: Collapse Panel | |
| +--------------------+ |
| +--------------------+ |
| | C: Bottom item | |
| | +-------+ +------+ | |
| | | D | | E | | |
| | +-------+ +------+ | |
| +--------------------+ |
