There could be several reasons for this. Some of the common ones are:

  1. The height property of the Dynamic Expander is not set to "Auto" or "Stretch".
  2. The parent container of the Dynamic Expander has a fixed height which is not allowing the Expander to grow.
  3. The content of the Dynamic Expander is not large enough to trigger the expansion.
  4. The expand/collapse animation is interfering with the actual height of the control.

To resolve this, try setting the height property of the Dynamic Expander to "Auto" or "Stretch" as applicable, ensure that the parent container has sufficient space to accommodate the expanded height, and check the content to ensure it can cause the expansion. If the animation is interfering, try disabling it or modifying it to allow for proper height adjustment.
