Hi Aayush,
We have checked the sample which you have provided. In that sample, you have set the Height for the control as Auto in the RowDefinition.Due to this, Height for the Items is set beyond the window size
To avoid this you can set the Height to ”*” for SfAccrodion. We have also created a sample for the same, please download the sample from the below link.
Sample:
SfAccordionUWPSampleWe have checked the behavior by replacing ListBox instead of SfAccordion. In this also we could see same behavior.
