How to enable field multiplier with URL validation?

I want to add a list multiplier that allows users to add numerous URLs. I looked at the different widgets but none of them give me the option to validate that entries are URLs only.

You can add a Text box and then set the URL validation, you can even set a hit such as "http://www.yourdomain.com"

Thank you, but how can I also allow them to add additional URL values (field multiplier option)?

You will have to use our dynamic field widgets such as this one: http://widgets.jotform.com/widget/dynamic_textbox because it's currently not possible in the basic text box field. Unfortunately, validation is not possible in this widget.

Also, this one: http://widgets.jotform.com/widget/field_multiplier. 

Here's our guide on how to add a widget to your form:
