How to create the custom datatype like textbox,richtext editor,mediapicker in SINGLE DATATYPE and is it possibility to cal individually like suppose i want to cal richtext editor only ...

Note: Because i want to display the sliding image for that one i need to select image along header and content which one belongs to specific image.

Other wise Is it possibility like if select the image after it will show the text box and then richtexteditor(like if select then only after show the textbox...)
