Vertical Timeline List

An Obsidian plugin that utilizes task lists to create a timeline... or something like a timeline.

Features

• Timeline Rendering — Any task list whose parent task has a t status (e.g. - [t]) is rendered as a vertical timeline in Reading View.
• Customizable Spacing — Adjust dot separation, line padding, and detail block spacing from the settings tab.
• Theme-aware Colors — Independent light- and dark-mode color values for the line, dots, hover state, and detail backgrounds. The active set switches automatically when Obsidian's theme changes.
• Collapsible Dots — Toggle whether timeline entries with details can be collapsed and expanded.

Manual

1. Download main.js, manifest.json, and styles.css from the latest release.
2. In your vault, create the folder .obsidian/plugins/vertical-timeline-list/ if it does not already exist.
3. Copy the downloaded files into that folder.
4. Open Obsidian, go to Settings → Community plugins, and enable Vertical Timeline List.

Usage

A timeline is denoted by a task list whose parent task has a t status. Nested list items become the timeline's entries. Further nesting under each entry becomes its details.

For example:

# Example
- [t]
  - 2020
    - Detail for 2020
    - Additional detail for 2020
  - 2021
  - 2022

renders as:

[!IMPORTANT] Add a space after the [t]. Without it, Obsidian does not recognize the line as a task and the timeline will not render.

Settings Reference

Spacing

Theme Colors

Each color has independent light- and dark-mode values. The active value applies whenever Obsidian's theme matches.

Behavior

Other Plugin Compatibility

Tested with:

• Dataview
• Tasks

Dataview

Internal links into nested timeline items work normally, but Dataview's TASK query only highlights a navigated-to task when every date in the note is already expanded in Reading View. The collapsible-dot option is therefore off by default. If you turn it on, this Dataview-specific highlight behavior will not work as expected.

Tasks

No issues were observed when using the Tasks plugin alongside this plugin. To exclude the timeline parent task from Dataview TASK queries, register t as a custom task status in the Tasks plugin and filter on that status.
