Can text fields be included in a jQuery dialog, and how can they be validated using HTML5 attributes like "required"?

Yes, text fields can be included in a jQuery dialog. To validate them using HTML5 attributes like "required", you can simply add the "required" attribute to the input field in your HTML code. This will make the field mandatory and trigger a validation error if it is left empty when the form is submitted. ```html <div id="dialog" title="Dialog Title"> <form> <label for="name">Name:</label> <input type="text" id="name" name="name" required> </form> </div> ```
