💡 As a result it may take up to several weeks or months to complete a review and merge your PR.

itsjeyd · 2023-11-23T13:58:26Z

@ArturGaspar Thank you for this contribution! Please let me know when internal review is done and the build is green.

@jmakowski1123 This is a user-facing change so we'll most likely need a feature ticket for it. Could you please confirm?

@ArturGaspar, this needs to pass through the client's UX QA first, so we can convert the PR to a draft for now.

I recalled that the legacy approach also scrolls the page down to the highlighted unit. This is particularly useful on mobile devices. We cannot rely on adding id={id} (e.g., to the <li> tag), but we could do something like this:

const sequenceLinkRef = useRef(null); const mutationObserver = useRef(null); // Scroll to the selected element. useEffect(() => { if (selected) { mutationObserver.current = new MutationObserver((mutationsList, observer) => { // Check if the element is already in the DOM. if (sequenceLinkRef.current && document.body.contains(sequenceLinkRef.current)) { sequenceLinkRef.current.scrollIntoView({ behavior: 'smooth' }); // Disconnect the observer once the element is found and scrolled to. observer.disconnect(); } }); mutationObserver.current.observe(document.body, { childList: true, subtree: true }); } // Clean up the observer on component unmount. return () => { if (mutationObserver.current) { mutationObserver.current.disconnect(); } }; }, [selected]);

sequenceLinkRef can be added to the li element.

However, this would only work for the sequences. We should think of something that could be reused for sections and sequences.

I did it without the MutationObserver and it appears to work as expected, and for both section and subsection links. Implementation is in src/course-home/outline-tab/hooks.js.

Why do we add the styles here instead of the grandparent li node?

Currently, it looks like this (I changed the color a bit to make this more apparent):

If we move it to li, it will look like this:

I initially did it that way because the first and last elements appear a bit taller than the others (due to the container having more padding), but I have changed this now and updated the screenshots in the PR.

jmakowski1123 · 2023-12-14T01:17:45Z

There is a larger project in play now to bring back the sidebar navigation experience, which was the original experience that was replaced by the breadcrumbs. Part of the consideration in that project is how many navigation options we need, and the breadcrumb pathway is being reconsidered in that context. We need to come to a decision first about which navigation experience the core product supports as the primary one, before investing in this. Suggest to put this on temporarily on hold. https://openedx.atlassian.net/wiki/spaces/OEPM/pages/3909779457/Feature+Enhancement+Proposal+Restore+the+left-sidebar+navigation+in+the+learner+experience

Agrendalath · 2023-12-15T14:46:51Z

@jmakowski1123, the project you mentioned sounds like a significant change. Do you know if there is any timeline for making this decision?

This PR brings back the legacy (non-MFE) experience - it only changes the action triggered by clicking on the text in the course navigation. If we decide to delete the breadcrumbs, the scope of that project won't be altered in any way by this change.
In the meantime, this PR gives us a (rather nice) side effect of highlighting specific parts of the Course Outline when redirecting users from external pages. Let's say we add a link like LMS_URL/course/{course_name}#{block_id} to the external page. When users click on it, they will be directed to the Course Outline page with the highlighted block_id (section/subsection), as shown on the screenshots. This is especially useful for the mobile experience, as the page is automatically scrolled to the highlighted element of the Course Outline.

Hey @jmakowski1123, based on a brief look at the wiki thread it seems like product review is still in progress. Do you have any updates about the timeline for this work?

itsjeyd · 2024-03-11T08:44:58Z

Hey @cassiezamparini, would you have time to help get the ball rolling again here in terms of product review?

cassiezamparini · 2024-03-11T08:49:45Z

@itsjeyd Sure thing! I'll add this to my to-do list for tomorrow :)

cassiezamparini · 2024-03-12T10:28:08Z

@itsjeyd It looks like this feature is on hold based on the comments from @jmakowski1123 in this thread. But I see you linked to my comment on the sidebar query. I'll follow up on this on the Wiki.

Also in order to do a product review, we need to follow the new process @ArturGaspar @Agrendalath - as outlined here. Please review the link above and follow the steps I mention below:

Create product proposal using a Template: Choose Your Template - Open Source Product Contributions
Create a Product Proposal ticket in the platform-roadmap GitHub repository (with a link to the product proposal etc). Note, tickets must be created here. The ticket will get auto-added to the Open edX Roadmap project board: Open edX Roadmap • openedx
The Submitter pings the Core Product Working Group in Slack (#wg-product-core) and shares the proposal. You can ping me once you've created the proposal and I can ping the Core Product WG on your behalf.

Please let me know if anything is unclear. We are still in the process of ironing out this new product review process, so your feedback will be welcomed.

In relation to Feature Enhancement Proposal: Restore the left-sidebar navigation in the learner experience:

Edward Zarecor:
Yes, the design phase has wrapped up and dev phase is starting now. It's targeted for GA in Redwood.

Thoughts?

itsjeyd · 2024-03-22T09:03:28Z

@cassiezamparini Thanks for looking into the status of product review for this PR!

Edward Zarecor:
Yes, the design phase has wrapped up and dev phase is starting now. It's targeted for GA in Redwood.

Thoughts?

I don't know what GA means, and I'm not sure how to proceed from here.

If the dev phase is starting now, does that mean we can consider this PR approved from the product perspective?

--

Either way, it's probably worth noting that my involvement here is limited to OSPR management (which currently doesn't include tracking individual steps of the product review process) 🙂

From that perspective, the main question to answer is the one above, i.e. whether product review is done and we can move forward with finding engineering reviewers for this PR.

As part of the project to reimplement the left sidebar navigation (full MVP spec here), I do not think it is necessary to invest in any legacy navigation experiences. The project to reimplement the left sidebar nav is a separate project from this proposal, and I think it will be possible to close this proposal as a result of the other project.

I'm assuming the point of proposing to revive the legacy breadcrumb experience is to make it easier for learners to see where they are in the course outline? This problem will be solved when we reimplement the left sidebar, as learners will be able to wayfind through the course outline without leaving the content.

The left sidebar will be revived for the Redwood release in June and will be the default experience out of the box. @ArturGaspar does this meet your needs, and if so, can we close this proposal?

ArturGaspar · 2024-04-19T14:41:43Z

@jmakowski1123 It is possible that the sidebar navigation would fulfil our needs, so I am converting this PR to a draft until the released version can be evaluated. Thank you.
