I am looking to create a calendar, like WordPress's Default calendar. That displays only Posts written by the current user.

I am moved by the workflow of creating my own widget like what was showcased in your https://unlimited-elements.helpscoutdocs.com/.

So my first trouble is how do I populate a calendar like, 

https://codepen.io/yur1y/pen/VwPVqgz

With post written by the currently logged-in user.

I will be playing around with the concepts you presented to discover the solution on my own. Meanwhile, I wanted to ask the question here to see if you had any insights.

Having the ability for a current user ability would be great!

I was able to get the calendar to work the way I wanted using the jet engine plug-in.

I do have another question, though. I am trying to add a "new post form" to a flip box Widget but am unsure how to integrate it. 

That would be awesome!

This is the page I am working on.

Currently, I have the image (front side of the flip box) then the form below. (the back of the flip box)

I have saved a Global Widget of the form Titled
New post Form, for FlipBox

I appreciate your help.

Thank you for your help in adding this feature. Unfortunately, I am unsure how to add it. I thought the attached file was an updated plugin I should install but received this error; The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature.

Unless I am missing something?
