# Timeline / Gantt View — Web app

A screen that displays tasks, milestones, or events along a horizontal time axis, commonly used in project management products to show schedules and dependencies.

## Items

### Time axis
A horizontal axis representing time, with clear date markers (days, weeks, or months depending on the zoom level)

_Tip: A timeline locked to a single timescale rarely fits all project sizes, and zoom controls let users shift between day, week, and month views as needed_

### Task bars
Horizontal bars representing each task or milestone, positioned according to their start and end dates

_Tip: A monochrome timeline becomes hard to parse at a glance — colouring bars by status, assignee, or category makes patterns visible immediately_

### Dependencies
Visual connectors between tasks that must be completed in sequence, showing which items are blocked by others

_Tip: Dependency lines can visually overwhelm a busy timeline, so showing them on hover or when a task is selected keeps the default view readable_

### Today indicator
A vertical line marking the current date so users can immediately see what is on track and what is overdue

### Milestones
Distinct markers for key dates or deliverables that are not duration-based tasks

### Drag to reschedule
The ability to move or resize task bars by dragging to update dates directly on the timeline

_Tip: A date tooltip while dragging gives users precise feedback on the new start and end dates_

### Row grouping
The ability to organise tasks by assignee, team, project phase, or another dimension
