Control Child Size

These Control Child Size options allow the automatic layout to override the current Width or Height of the child objects. If you select it without selecting the corresponding Child Force Expand property, your child objects will no longer be visible (unless it has a Layout Element component with Preferred Width specified).

If you do not set this property, it is possible that the children will draw outside of the parent's Rect Transform, that is, if too many children exist.

Since this property depends on the Child Force Expand property, examples of the Control Child Size property are presented in the next section.
