Labels

A feature that lets you display a label on each side of a Gantt task bar. See Labels for more information.

new Gantt({
   features : {
       labels : {
           // Label rendered before the task bar with content from the record's `name` field
           before : {
               field  : 'name',
               editor : {
                   type : 'textfield'
               }
           },
           // Label rendered below the task bar with custom content
           // from a renderer
           bottom : {
               renderer : ({ taskRecord }) => `ID: ${taskRecord.id}`
           }
       }
   }
});

This feature is disabled by default. For info on enabling it, see GridFeatures.
