Drag whit limit

hi to all!!

tnk in advanced

Could you explain me more in a more detaild way what are you trying to do?.
I’m not sure if I understanded well, but I think you are trying to make something to go down and up in a page, like this:

Now, for this, you can use the separate objects behavior, the put, the object, build somekind of box around it, and put it around it, so it doesn’t move to other place’s. Now, for attaching the text/images/whatever you want to put in there, I’m not quite sure what to do.
You can try by setting the position of the text to some point of the bar…
