Draggable

Implements drag & drop functionality

Using

Simple example of draggable component to swap containers.

Template:

<div class="drag-scroll-test">
	<div *ngFor="let obj of content; let i = index"
		[scrollContainer]="'.drag-scroll-test'"
		pipDrop="true"
		pipDrag="true"
		(dropSuccess)="onDropSuccess($event, i)">
		<div>
			<p >{{ obj.name }}</p>
		</div>
	</div>
</div>

Handler:

onDropSuccess(event, index) {
    const otherObj = this.content[index];
    const otherIndex = this.content.indexOf(event.data);
    if (otherIndex === index || otherIndex === -1) return;

    this.content.splice(otherIndex, 1);
    if (index > otherIndex) this.content.splice(index, 0, event.data);
    else this.content.splice(index + 1, 0, event.data);
}

Styles:

[pipDrag] div {
    padding: 8px;
    box-sizing: border-box;
    transition: all .35s ease;
    height: 85px;
}

[pipDrag].pip-dragging {
    opacity: 0.95;
}

[pipDrag].pip-dragging div {
    height: 85px ;
}

[pipDrop] {
	position: relative;
}

[pipDrop] {
    transition: padding .35s ease;
}

[pipDrop].pip-drag-enter:not(.virtual) {
    padding-bottom: 85px !important;
}
