How do I create required fields on a form?

In the forms manager, you can create simple HTML forms easily. However, the addition of required fields must be added through the source code currently. To do this, you just need to insert the following attributes into the <input > tag (message="value" required="true")

An example is listed here:

<input message="Company Name is Required" required="true" name="LastName" id="txtCompany" class="text" type="text"

This will result in an alert when someone tries to submit the forms without completing the required fields.
