How to change plus.gif / minus.gif to use a complete different image


I am using the tree grid and I want to change this icon :

It’s an image tag with plus.gif. I want to use svg instead so it scales up properly, but I can’t do that if their is a gif.


In the options their is only an option to change the path and not the actual image being used.

Anyway to change the image without changing source code?


Unfortunately it is not available to change the name of the using icon. Only the “plus.gif”/“minus.gif” can be used
