Is there a way to create a specific clicking area in a Vertical Box ?


I’m creating a main menu for my game, but there’s a problem with the “clicking area”.

Let me show some screenshots :

I’m using this image in “The Vertical Box”.
Like you can see on my screenshot, I’m using a text with a light spread and I have to enlarge this image to avoid the crop of the light spread.
When I launch my game, the clicking area is too large because of the image size, I need to resize this clicking area, is there a way to do it without resize the image it self ?

Thanks anyway ! (:
