How to get collapse button for the below requirement?
Plz find attachement.
I need to implement collapse for my code also please find Demo.png which gives you an idea.
This code is developed in flex3.
Try to implement my code to the required format.
Rectangle,Circle,Square these images are available in src\images
rest are available under project directory dir\images\delete.png etc..
Thanks
