Hi Nagendra,
Currently we don’t have resize functionality with Sidebar. This requirement had already been considered as a feature from our end, but we do not have any immediate plan to implement this feature.
At the planning stage for every release cycle, we review all open features. Usually, Syncfusion will plan and implement the features based on feature rank, customer requested count, and volume wish-list. We will let you know when this feature is implemented. The status of implementation can be tracked through the below portal link:
Please let us know if any concerns.
Regards,
Keerthana R.
