How can i create a popup menu when a button is clicked?

You could create a boolean that checks whether or not the button has been pressed, and then utilize the OnGUI function:

     public class ClickExample : MonoBehaviour
     {
         public Button yourButton;
        //declare a boolean
        public bool buttonisclicked;
         void Start()
         {
             Button btn = yourButton.GetComponent<Button>();
             btn.onClick.AddListener(TaskOnClick);
            //set to false on start, may not be necessary, I just can't remember if C# will return 1 or 0 for undefined booleans 
             buttonisclicked = false;
         }
     
         void TaskOnClick()
         {
             Debug.Log("You have clicked the button!");
             //set our bool to true
             buttonisclicked = true;
         }
         
         private void OnGUI()
        {
           //check if our button click boolean is true
            if(buttonisclicked)
           {
                //create gui menu, refer to linked documentation to learn how to create gui elements via script, and learn about various styling techniques
           }
        }
     }

Good luck with your project!

Hi @Milito007,

Done something similar to thing you look for. In my project I used Animator.

Firstly setup parent game object, with main button. Then as a child of it attache another-this will make present all actions after click: "drive down", become visible (by changing alpha value from 0))... etc.

You will just need 2 animations, not looping, trigger based... one for opening menu, second for hiding it (could be opening with, speed -1).

Hope will help. Belive this way is easier than coding.
