Hi,

You could use https://bryntum.com/products/gantt/docs/api/Grid/column/Column#config-renderer and put a condition inside and and add your logic inside of your condition

Example

renderer : ({ record }) => {
	if (!record.isLeaf) {
		// logic here
	}
}

https://bryntum.com/products/gantt/docs/api/Gantt/model/TaskModel#property-isLeaf

I hope this will help

That would be better done with an ActionColumn: https://bryntum.com/products/gantt/docs/api/Grid/column/ActionColumn
