hello Sorry for answering so far but yesterday was complicated my day , thank you all for your answers, the solution was the proposal to Jonathan , you were right , the delay pruduce jQuery plugin ( waitUntilExists ) worked ... makes me remember some years ago when programming in ActionScript ... apparently needed this time to be reflected in the document body . One more time thank you all and especially to Jonathan for his contribution , I hope not give more tin with details and I'm glad I could use your Draggable plugin , which I think is great . Greetings .
