Use

The resizeable element in the component needs the Resizeable-Directive and some properties. Every single Edge need it's own space with a Rezise-Directive.

<div class="relative flex top-32 h-32 w-32 m-auto bg-red-500 box-border" [ngStyle]="style" Resizeable [validateResize]="validate" [enableGhostResize]="true" [resizeSnapGrid]="{ left: 50, right: 50 }" (resizeEnd)="onResizeEnd($event)">
    <div class="absolute h-1 w-full top-0 cursor-row-resize" Resize [resizeEdges]="{ top: true }"></div>
    <div class="absolute h-full w-1 left-0 cursor-col-resize" Resize [resizeEdges]="{ left: true }"></div>
    <div class="absolute h-full w-1 right-0 cursor-col-resize" Resize [resizeEdges]="{ right: true }"></div>
    <div class="absolute h-1 w-full bottom-0 cursor-row-resize" Resize [resizeEdges]="{ bottom: true }"></div>
</div>

The position of the element will be set by the style.
