How can I convert a table of contents with hyperlinks (to web pages) into an odt or odm document?

Is it possible to create an odt document that contains all linked pages from the table of contents of a document from the Internet, e.g. the table of contents at https://docs.gimp.org/2.10/en/? (It consists of organized headings, with a hyperlink behind each heading.)

Is it possible to do this when such a TOC (or parts of it) has been copied into an odt or odm document, so that the hyperlinks associated with the headings become hyperlinks to the headings in the generated document? If it is possible, what do you recommend: odm or odt?

Is it possible to do this so that the copied TOC becomes the main document and all the chapters (of a given order with everything below them) from the links become sub-documents of the main document (with some generic names)? (This would mean that everything of the heading order lower than say 2 would go the the same file as the heading 2 to which they belong).

Is your target: You have a local Writer file with links into the internet? Or would you like to export the entire document and its structure into html and upload into the internet?
Please specify your wishes.

Certainly not an .odm which is the extension for a master document.

Now, why would you translate such a page (or full site) into an .odt? I had a look at the HTML source. All links are relative (to the current page). The simplest way, if you want to have a local copy, is to grab site contents with a utility such as wget (Linux CLI mode) to store it in some user directory.

Once this is done, use your web browser to open a file (the HTML for the page, index.html for instance). Then navigate clicking on the links. The browser will use file:// protocol instead of http:// unless some links point to external sites.

The page you reference in your question seems to be plain ol’ HTML without scripting. Don’t forget to download also the CSS stylesheets if the site grabber does not do it.
