If you are looking to extend your Webflow form with more input types read on.
Here is the link to my custom form page where I have demonstrated what can be done when you combine the Webflow form widget and the embed widget. http://sand-box.webflow.io/custom-forms
To use this technique you will need the from block on your page. You can learn more about the [Webflow form in the this tutorial][1].
Your form is not ready to go. You will receive this information in the Webflow dashboard and in your email.

Yes you can use custom styling. The easiest way is to create a class on a native form element and style it in the editor. Then apply it to the embed code. Like this; <label for="date">Date:</label> <input class="w-input yourclassname" type="date" name="date">
Note that even though you might use capital letters in your class naming; the class is outputted all lower case, because CSS is not case sensitive.
But I need the min value to always be the current date, so I don’t want to manually go in everyday and change the min value to today’s date…I hope I’m being clear?
