How to Change Stroke Style Color when Dragging Node into Vue Diagram?

This article explains how to change the stroke style color when dragging a node into the Vue Diagram. Syncfusion® Vue Diagram provides the ability to customize the style of the highlighter. You can modify the stroke color of the highlighter when dragging and dropping a node over another element by using the .e-diagram-highlighter class.

Enabling Highlighter for a Node

To enable the highlighter for a node, you need to set the allowDrop constraints for that specific node. This can be achieved by modifying the node’s constraints as shown in the following example:

{
    id: 'node1',
    offsetX: 300, offsetY: 300,
    height: 100, width: 100,
    constraints: NodeConstraints.Default | NodeConstraints.AllowDrop
}

Customizing the Highlighter Style

The highlighter’s style can be customized using CSS. For instance, to change the stroke color of the highlighter, you need to define the style for the .e-diagram-highlighter class as follows:

<style>
   .e-diagram-highlighter {
       stroke: blue;
   }
</style>
