<s>[INST] How to add a scrollbars to unity text mesh pro input field in unity [/INST] Install TextMeshPro package from the package manager, it has a built in input field that supports scrolling out of the box without any coding.

It is also the future of unity's text.</s>\ <s>[INST] Could you please provide a more detailed guideline? [/INST] Here is a step-by-step guide to add a scrollbar to a Unity Text Mesh Pro Input Field in Unity:

Create a new Unity project and import the Text Mesh Pro package. You can do this by opening the Package Manager (Window > Package Manager), selecting the "All" tab, and searching for "Text Mesh Pro".

Create a new Canvas in your scene and add a Text Mesh Pro Input Field to it. You can do this by right-clicking the Canvas and selecting UI > Input Field.

Create a new Scrollbar by right-clicking the Canvas and selecting UI > Scrollbar.

Change the Direction of the Scrollbar to Vertical. You can do this by selecting the Scrollbar in the hierarchy and changing the Direction property in the Inspector.

Set the Viewport Size of the Scrollbar to 0. This will hide the thumb of the Scrollbar and only show the scrollbar background.

Create a new script and attach it to the Text Mesh Pro Input Field. In this script, you will add code to track the Input Field's content size and update the Scrollbar's size and position accordingly.

Here is a code in csharp: 
using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class ScrollbarUpdater : MonoBehaviour
{
    public Scrollbar scrollbar;
    public TMP_InputField inputField;

    private void Update()
    {
        float contentHeight = inputField.textComponent.preferredHeight;
        float viewportHeight = inputField.GetComponent<RectTransform>().rect.height;

        scrollbar.size = viewportHeight / contentHeight;
        scrollbar.value = 1 - scrollbar.size;
    }
}


Assign the Scrollbar and Input Field components to the corresponding variables in the script. You can do this by dragging the components from the hierarchy to the script's properties in the Inspector.

Test the project. You should now see a Scrollbar appear when the content of the Input Field exceeds the viewport height.

Optional: You can customize the appearance of the Scrollbar by changing its properties in the Inspector, such as the color, handle size, and background size.

This guide provides the basic steps to add a scrollbar to a Unity Text Mesh Pro Input Field. You can further customize and refine the implementation to fit your specific needs and requirements.</s>
