gantt-task-timeline-react

gantt-task-timeline-react

📌 This is a customized fork of gantt-task-react.

Customizations

• Support for Multiple Tasks in a Single Row • Renders multiple bars in the same row using siblingTasks • If task dates do not overlap, they are placed on the same line; overlapping tasks are stacked vertically • Custom Y-position calculation implemented in bar-helper.ts

📌New Task properties

 siblingTasks?: Task[]; // Used to render multiple bars within the same row

• Custom Dependency (Arrow) Rendering • Draws arrows between tasks based on dependencies • Supports arrow connections between siblingTasks within the same row

• Automatic Line Wrapping Inside Bars • If a bar is too narrow, the task name is automatically wrapped using • If there are multiple lines, the bar height expands dynamically (up to rowHeight) • Text remains vertically centered within the bar
