Here is this plugin: https://sourceforge.net/projects/jquidragcollide/
Sadly, this not works with jQuery 3 and the latest UI version. Is there any modded version, that works?
Update: I try use this plugin with jQuery 3.3.1 and UI 1.12.1.
Here is my code:
<style>
.pin {
width: 100px;
height: 100px;
background-color: #65C02F;
margin: 7px;
border-radius: 0px;
-moz-border-radius: 0px;
-webkit-border-radius: 0px;
box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
-moz-box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
-webkit-box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
transition: box-shadow 0.2s;
}
.pin.placed.boundary {
box-shadow: 0 0 0 15px rgba(0, 0, 0, 0.4);
-moz-box-shadow: 0 0 0 15px rgba(0, 0, 0, 0.4);
-webkit-box-shadow: 0 0 0 15px rgba(0, 0, 0, 0.4);
}
</style>
<script src="jquery-3.3.1.min.js"></script>
<script src="jquery-ui-1.12.1.js"></script>
<script src="jquery-collision.min.js"></script>
<script src="jquery-ui-draggable-collision.js"></script>
<script>
// Example
$( function() {
// make pins draggable (using jQuery UI)
$(".pin").draggable({
// apply collision effect (using collision plugin above)
obstacle: ".placed",
preventCollision: true,
// optional, snap to pixel grid (using jQuery UI)
// grid: [113,109],
// animate on start of drag (using jQuery UI)
start: function(e, ui) {
$(this).removeClass('placed'),
$('.placed').addClass('boundary');
},
// animate on end of drag (using jQuery UI)
stop: function(e, ui) {
$(this).addClass('placed'),
$('.placed').removeClass('boundary');
}
});
});
</script>
<div class="pin"></div>
<div class="pin"></div>
<div class="pin"></div>
<div class="pin"></div>
I got the following error:

Thanks for help.
So, I found the solution, that work with the latest version of jQuery and its latest UI.
I wrote the method, what have to do step by step. With these the plugin will be useful and work properly. (I didn't test any function, only the draggable.)
step: download the JQuery Collision plugin (required to run the draggable plugin), from here: https://sourceforge.net/projects/jquerycollision/
step: download the JQuery UI Draggable Collision plugin, from the link above
Ps. Spec. thanks to the members, those gave negatives, without them, it would not have been possible.
