using System.Collections;
using UnityEngine.UI; // Required when using UI elements.

public class ExampleClass : MonoBehaviour { public Transform MyContentPanel;

//Sets the flexible height on on all children in the content panel. public void Start() { //Assign all the children of the content panel to an array. LayoutElement[] myLayoutElements = MyContentPanel.GetComponentsInChildren<LayoutElement>();

//For each child in the array change its LayoutElement's flexible width to 200. foreach (LayoutElement element in myLayoutElements) { element.flexibleWidth = 200f; } } }
