Hi,
You can use something like this in your custom js:
function scrollToField(fin){
var container = jQuery("#s4-workspace")
container.animate({
"scrollTop": jQuery("#dffs_" + fin).offset().top - container.offset().top + container.scrollTop()
});
}
Now you can scroll to a selected field by using this function call:
scrollToField("Your_Field_Internal_Name");
