I am searching for an HTML div that is free floating and can be dragged and positioned anywhere on the page without being affected by other elements. It's okay if the element blocks the view of elements below, and it would be great if there is a minimizing capability. Are there any libraries that offer this functionality?
After searching on Google, I only found items that can be dragged from one position and placed inside another. I couldn't find any free floating libraries.
To enable dragging functionality, you need to utilize the draggable attribute along with some JavaScript logic. Please note that the following code example uses pure JavaScript, not AngularJS.
function drag_start(event) {
var style = window.getComputedStyle(event.target, null);
event.dataTransfer.setData("text/plain", (parseInt(style.getPropertyValue("left"), 10) - event.clientX) + ',' + (parseInt(style.getPropertyValue("top"), 10) - event.clientY) + ',' + event.target.getAttribute('data-item'));
}
function drag_over(event) {
event.preventDefault();
return false;
}
function drop(event) {
var offset = event.dataTransfer.getData("text/plain").split(',');
var dm = document.getElementsByClassName('dragme');
dm[parseInt(offset[2])].style.left = (event.clientX + parseInt(offset[0], 10)) + 'px';
dm[parseInt(offset[2])].style.top = (event.clientY + parseInt(offset[1], 10)) + 'px';
event.preventDefault();
return false;
}
var dm = document.getElementsByClassName('dragme');
for (var i = 0; i < dm.length; i++) {
dm[i].addEventListener('dragstart', drag_start, false);
document.body.addEventListener('dragover', drag_over, false);
document.body.addEventListener('drop', drop, false);
}div {
position: absolute;
left: 0;
top: 0;
/* set these so Chrome doesn't return 'auto' from getComputedStyle */
width: 200px;
background: rgba(255, 255, 255, 1);
border: 2px solid rgba(0, 0, 0, 1);
border-radius: 4px;
padding: 8px;
}
body,

$scope.list1 = {title: 'AngularJS - Drag Me'};
$scope.list2 = {};
});
