Date Calendar Style

Is there a way to edit the style of the calendar?

When I go to gravitywiz and look at the perks demo, the calendar has a different style. Why is this? Is it because of the perk purchase? How can I get this style instead of the one above?

Hi David. Where can we see your current datepicker field? I did not see a link in your post.

Here is my current calendar view.

Thank you. I wanted to be sure you are using a later Gravity Forms version that has access to the style being shown by Gravity Wiz (you do.) Gravity Wiz customized theirs with CSS. You would need to do the same. If you are good with CSS, you can inspect the elements in the calendar with the browser developer console and then add your own CSS. You can also inspect the CSS of the Gravity Wiz page to see how they did it.

If you have any other questions, please let us know.
