how to create a custom emailfield

Try this:

var placeholder = sym.$("placeholder")

placeholder.html("");

inputEmail = $('<input />').attr({'type':'text', 'value':'', 'id':'email'});

inputEmail .css ('font-size', 14);

inputEmail .css ('width', 250);

inputEmail .appendTo(placeholder);

You can get the value of the input with: var myEmail = inputEmail.attr("value");

For example, below I get the value and display it in a field on a click event.

function updateTxt(){

          var myEmail = inputEmail.attr("value");

          sym.$("email").html(myEmail);

}

sym.$("btn").click(function(){

          updateTxt();

});

If I understand what you want - a fiel for an email address.

Here is a link to the sample: https://www.box.com/s/xvvr3vjw19rg0dunvj40

Otherwise, if this is not what you want, please explain.
