Multiple Colums

You need CSS for that. Here is CSS example

.class_name {
	width:50% !important;
	padding-right:10px;
	float:left;
}

Add this to your CSS document at the end.

Now, in your form window, for the left column start by putting the div element:
<div class="class_name">

Then in it put the form elements that you need (email, name, phone etc,), After that close it with the:
</div> element

Do exactly the same for your right column (you can use the same class)
