Drag and drop

Responsive how sir?

If you mean scaling like  website storyline doesnt support this it merely scales the whole course look for the option in the player settings.

Hi, Souhail -- Thanks for reaching out and if you have a file you'd like to share to help illustrate what you have in mind, please feel free to upload here by using the grey ADD ATTACHMENT button in the bottom left of the reply box. 

I want to know if it's possible to do the same with storyline,
Thank you

If you drop multiple objects on an area and set it to stack the answers it will list them in a line. It wont resize the box. Therefore make the box big is the easiest solution.

There may be a way to do this dynamically if you target box had states of different sizes getting bigger with each state. As more answers are dropped the box state changes to display bigger.

You'd have to fins a trigger variable combination to track answers dropped on a target, total those in a number variable, and have that number change the state of the target to get bigger/smaller as answers are dropped

thanks for your reply,

I chose the easiest solution , and make a bigest box...

Thanks Souhail for sharing the images and I'm glad that Tim's solution will assist you.
