With the recent, perhaps temporary (?) installation of a bread crumb trail at the top of the standard TWiki view template, I need to think about how this works and how to take best advantage of it.

It seems the bread crumb trail is based on the parents of a page. (confirmed)

The parents of a page are based on (I think) the page from which a new page is created by putting a WikiWord on that page and clicking on the question mark. (confirmed)

I assume if that page had parents, then those will show up as grandparents of the new page. (confirmed)

I think the bread crumb trail shows more than just the parents of a page (like grandparents, etc.) -- I must test this (among other things) to confirm (confirmed -- at least to grandparent level -- will watch for pages with great grandparents).

I created this page by typing a new (WikiWord) page name into the browser's address bar. Because of this, I don't believe it will have any parents (confirmed) -- the bread crumb trail will show TWiki . <webname> . <topic(page)name> (confirmed).

So, assuming all of the above is true, I should make it a point to always create a page by creating a new page from the page which I want to be considered the parents of the new page. I guess I can change parents after the fact, but it seems like a royal PITA.

I have this feeling I'm creating a convoluted and meaningless pattern of "bread crumbs", at least in some cases.

For some examples of pages with (sometimes) meaningfull bread crumb trails, see BltTermsToDefine and follow links to some of its subpages.


  • The bread crumb trail can cross webs. In other words, if you create a page on a different web from a page (by clicking on the question mark after a "web qualified" square bracket link (Sandbox.TestRhk01 -- confirmed) (and maybe even if "web qualified but not square bracket link (TestRhk02 -- not tested yet)), the bread crumb trail will include these cross web links (and show them correctly).

  • At least in the standard TWiki template, the correct / complete bread crumb trail displays only in view, not in preview.
