What does it do?

Added pageSize props which indicate how many elements will render initially on the dropdown. When the scroll is near the end of the list, it automatically renders the next group of elements in the dropdown.

Fixes #498

• For this Issue (Full tree not displayed after selecting a node in a large tree, closing and reopening #498): need to provide pageSize={10000}. This will solve the problem of this issue
