I am hoping someone can help me. I am trying to implement a collapsible panel. I have done so far is set the HorizontalHeaderAlignment to the right. I have added header text and an image. I then set the horizontal stretch property to true. So, at this point I have almost achieved my goal. What I would like, is to have image and header text left justified. I can't seem to find any other properties that will help me do this. Is this doable? I have included a screenshot of what I have been able to do so far. Thanks.
