Auto scroll content with selected item

Hello,

I have a dropdown menu, working fine:



Using mouse/touch. But, I would like to use now the keyboard/joystick with buttons to control it.

I can select the dropdown items and navigate, you can notice the fourth item is selected ("Atlantis"... in red).

But, if I go down to the next item bellow it... using only keyboard for example... the content dont scrolldown automatically...

How can I do that?

 

set slider position manually to item position y / scroll bounds height

 

Where do I have the info of which item is selected?

 

Well, I solve this way

if (Input.blablablagetbuttondown)

{

    TemplateViewPortContentRectTransform.anchoredPosition += new Vector2(0,

    TemplateViewPortContentItemRectTransform.sizeDelta.y);

}

With some name changes to explain better what are the objetcs... And equivalent code to go up.
