Add EuiTimeline #5730

elizabetdev · 2022-03-17T19:47:36Z

Summary

This PR closes #4492.

There is one implementation in Kibana that is using the EuiComment to create a vertical timeline like the one mentioned in #4492 - a vertical timeline to indicate the life cycle of data.

I could "fix" some props in EuiComment to make the component more open. But IMO the purpose of the component is not meant to be used to create a vertical timeline that indicates the life cycle of data. But to be used to add user/system comments and updates.

EuiTimeline

So this PR adds a EuiTimeline component where consumer just need to pass an array of EuiTimelineItem. Each EuiTimelineItem accepts:

icon: main icon that appears on the left side.
children: event content. You can pass any node.
verticalAlign: vertical aligns the event with the icon

EuiAvatar

Added new color option "subdued" to EuiAvatar

@cchaos I went through your review. I also changed a bit the logic of the timeline icon lines in 181da63. The way the timeline was built before was assuming that larger components would always have the alignment "top". Now it works no matter which alignment is passed.

I also added a recommendation for the icon size in 28496cb.

🙌 Nice catch!!! I'll do a final review later today

Just some last-minute bugs found from the last round of updates. Also, I'd checkin with @1Copenut to see if he knows of any a11y guidance around timelines.

cchaos · 2022-04-11T19:59:52Z

src/components/timeline/timeline_item_icon.tsx

+
+  const iconRender =
+    typeof icon === 'string' ? (
+      <EuiAvatar color="subdued" name={icon} iconType={icon} />


Since consumer's can now pass simply the iconType as the icon and it you're just passing that on as the name of the EuiAvatar, I think we should do one of two things:

Require an event aria-label (or something) like we require for EuiButtonIcon's which in this case would just pass down as the avatar name.

See if an empty string is valid as an EuiAvatar name instead of passing down the icon name.

Just passing the icon name doesn't really present the user with useful information. They care more what the icon represents not what it is.

And if it's purely decorative, then this extra tooltip is just more noise.

@cchaos, this was fixed in 2c9c667. I added an iconAriaLabel prop that only works when the icon is passed as an IconType. The prop is not required. If not passed we assume the icon is decorative.

Thank you for the heads up @cchaos. I looked over the code before our team sync and didn't see anything that would be an a11y issue on first pass.

I have an idea about exploring this component as an ordered list with list items to provide contextual cues for screen readers. That idea is a pure enhancement, so I'll add it as a research ticket and reference this PR.

🙌 LGTM! Let's get it in the hands of a consumer. We can follow up with proper a11y since we're labelling it "Beta". But be sure to do so.
