Expand TextMeshPro / Container automatically

So i know you can set a Text Mesh Pro to auto-size the font to fit it's parent container BUT what i want is the opposite, to keep a font size and expand the parent/s to fit the text, this is my text panel, i use it mainly for tooltips/show info (first image).

The second image is how i'd like it to work (fit container to text mesh pro size/lines).

And the third image shows how it works and how it should work.

I've tried messing around with vertical/horizontal layouts, content fiters, layout elements... with no luck.

Hope to find some help here, thanks!

 

Hi again, i'm still trying to do this
Help is <3

 

I just found a way to change the rectTransform to the overflowing text size.

public RectTransform LineOneText;

if(LineOneText.GetComponent<TMPro.TMP_Text>().isTextOverflowing){//change rectTransform only if text overflows
Vector2 temp = LineOneText.sizeDelta;
temp.y = LineOneText.GetComponent<TMPro.TMP_Text>().preferredHeight;
LineOneText.sizeDelta = temp;
}


though you could also just do it like this instead:

//change rectTransform to preferredHeight
Vector2 temp = LineOneText.sizeDelta;
temp.y = LineOneText.GetComponet<TMPro.TMP_Text>().preferredHeight;
LineOneText.sizeDelta = temp;

 

You don't need any code to do this. Put Tmp Text as a child of the game object with a Layout Group and Content Fitter components. Choose Preferred Size for horizontal/vertical. In combination with Layout Element and Preferred Width/Height you'll have full control of the parent's size
