I am using the following:
https://troolee.github.io/gridstack.js/
For each grid-stack-item, I have a grid-stack-item-content div. Within each, I have 2 divs with class .panel-header that has the title of the box/panel and a textarea under that. The issue is, the textarea is never fitting the whole height of the panel even when I set the height of the textarea to be 100% in both width and height.
