High charts Gantt Drag and Drop is slow

Hi Team,
We are using High charts Gantt module in React Js our core business requirement is when one milestone is moved/dragged need to move further milestone dates feature is working however it is little slow while performing operations using below properties in configurations
1.dragDrop: {
draggableY: false,
draggableX: userRole ? isDraggable : false,
},
2. dataLabels: [
{
enabled: true,
formatter: function() {
return dueDateInMilliseconds
? `<img class="due-date-flag" src="/icons/due-date-flag.svg"><div class="due-date">${getMilestoneDate(this.point.start)}</div>`
: '';
},
useHTML: true,
align: 'left',
},
],
For showing date inside milestone. Please find the attached screenshot for your reference. Thanks

Re: High charts Gantt Drag and Drop is slow

Hi,
Welcome to our forum and thanks for contacting us with your question!

There aren't any images in attachments, could you send them again?

Are you using our official React wrapper for React?

Sorry, I can't replicate your problem, I need see your example in the working demo.

I'm waiting for news from you.
Best regards.
