I am very new to this work. I am just trying to display a simple pop up with selected data.i mean to say that if i have a registration form on clicking of submit i need to get a pop up stating all the selected entries in that pop up.
Link share by Baharul should get you started with the control.
Just to add on the use case. Use a bean to map all the fields of the form and on click of submit you can use the same bean to display the data on Modal Box.
