Hi, I’m integrating Collabora Online (read-only mode) into a React app via iframe. I’m trying to use the Linking API to navigate to a specific bookmark when the document loads. According to the documentation: > You can open document at specific target by using additional URL parameter for example: `&target=Table1|table` I have a DOCX file with a bookmark (visible in MS Word via Insert → Bookmark). According to `extract-link-targets` output, bookmarks are returned without a type suffix, just the name. So I’m passing `&target=bookmarkName` in the iframe URL. **What happens:** The document opens normally, but there is no scrolling to the bookmark position. The viewport stays at the top of the document. **Questions:** 1. Is `&target=` supposed to scroll the viewport to the target location, or does it do something else? 2. Does it work in read-only mode, or only in edit mode? 3. Is there a known issue with this feature? We couldn’t find any community discussion about it actually working. We’ve already investigated `Action_Find` (highlights but doesn’t scroll), `.uno:GoToPage` (opens a dialog), and postMessage navigation — all dead ends per previous forum discussions. Thanks ---

hi @KereatVais welcome to collabora online forum Based on my analysis of the codebase, here’s what I found: > [@KereatVais](#): > > 1 . Is `&target=` supposed to scroll the viewport to the target location, or does it do something else? **Yes, it’s supposed to** , but there’s a bug/implementation issue. The code in `browser/src/layer/tile/CanvasTileLayer.js` sends `.uno:OpenHyperlink` with `#targetName` as the URL. However: - The documentation says to use format `&target=Table1|table` (with type suffix) - The code **doesn’t actually parse the type suffix** - it just prepends `#` to whatever you pass - The `extract-link-targets` API returns bookmarks **without** a type suffix (just the name) This mismatch means bookmarks from `extract-link-targets` won’t work correctly with `&target`. > [@KereatVais](#): > > 2 .Does it work in read-only mode, or only in edit mode? The code has no explicit read-only check that would prevent this from working. However, `.uno:OpenHyperlink` may behave differently in read-only mode. > [@KereatVais](#): > > 1. Is there a known issue with this feature? We couldn’t find any community discussion about it actually working. **Yes**. This aligns with: - [Stack Overflow question (Aug 2025)](https://stackoverflow.com/questions/79749851) - specifically about viewport not scrolling to highlighted content - [Issue #10798](https://github.com/CollaboraOnline/online/issues/10798) - Cannot create internal links to headers/index - Multiple forum posts about bookmark/jump functionality not working The `goToTarget()` function uses `.uno:OpenHyperlink`, which is designed for **hyperlinks** within documents, not for navigating to **bookmarks**. This is fundamentally the wrong mechanism. Workarounds you could try: 1. Use `&target=bookmarkName|bookmark` (add the `|bookmark` suffix) - though the code doesn’t parse it, it may help internally 2. Use the `search` parameter with `highlight=true` - this at least highlights text, though doesn’t scroll either 3. Consider filing a bug/feature request at [GitHub · Where software is built](https://github.com/CollaboraOnline/online/issues) to properly implement bookmark navigation Thanks Darshan ---
