Template-protected edit request on 30 October 2017

Hi, could the html markup in this template be fixed? See https://en.wikipedia.org/w/index.php?title=Template:Flatlist/sandbox&oldid=807871376 for a correct fix where the div is closed outside the if section instead of adding an extra closing div in the noinclude section.

:{{Re|Tholme}} I'm not sure your change is correct. When used without parameters, typically using the redirect {{tl|startflatlist}}, the template is required to leave the div open so that the end of the list can be marked with {{tl|endflatlist}}. -- John of Reading (talk) 17:09, 30 October 2017 (UTC)

::You are right, so don't do the change. Tholme (talk) 17:35, 30 October 2017 (UTC)

Display issue on mobile version

Raised Wikipedia:Village pump (technical)#Template:Flatlist does not display correctly on mobile in case if anyone is not aware. ネイ (talk) 16:45, 24 May 2020 (UTC)

: I added the class hlist-separated, which is present in {{tl|hlist}} and appears to make bullets render in mobile. Report any bugs here. – Jonesey95 (talk) 17:57, 24 May 2020 (UTC)

:: {{ping|Jonesey95}} Nested flatlists do not display closing parentheses on mobile; see for example "People or cargo transported" in the infobox at Atlas V. I get the same issue with {{tlx|hlist}}, I'm guessing because they use the same class. {{small|{{ping|ネイ}} I redirected the link in your comment to the archive.}} Hairy Dude (talk) 14:44, 20 February 2022 (UTC)

:::I don't know if second-level asterisks are formally supported in this template. I have added a case to the testcases, showing that there are missing closing parens after "Curiosity" and "Quasar" [https://en.m.wikipedia.org/wiki/Template:Flatlist/testcases#With_second_level_of_asterisks in mobile view]. – Jonesey95 (talk) 18:25, 20 February 2022 (UTC)

::::One note: Removing "hlist-separated" from the class declaration removes the bullets and restores the closing parens. See the sandbox version in the mobile testcases link above. – Jonesey95 (talk) 23:16, 20 February 2022 (UTC)

Why the extra closing tag?

Is there a purpose for the seemingly stripped

after the ? —Anomalocaris (talk) 22:59, 22 December 2020 (UTC)

:I think it's because there is no {{para|1}} in the template page itself. When you say "seemingly stripped", what do you mean? To me, it appears to match the opening tag just fine, but it is needed only on this page (hence the noinclude tag). Is that closing tag causing an error somewhere? – Jonesey95 (talk) 00:18, 23 December 2020 (UTC)

::I see

just before }} and then another one inside ..., which, to my naive eye, seems to be stripped. I think you were trying to explain this to me above, so maybe you'll have to explain it at a more basic level, since I don't know why I should care about {{para|1}}. Anomalocaris (talk) 23:14, 28 December 2020 (UTC)

:::The template may be used in two differing ways: (i) like the first example at Template:Flatlist#Examples, where the entire list is passed into {{tlx|flatlist}} through its {{para|1}} parameter; (ii) like the example at Template:Flatlist#Alternative syntax, where the list is placed between {{tlx|startflatlist}} and {{tlx|endflatlist}}. In the case of (i), the single use of {{tlx|flatlist}} wraps the list in {{tag|div|params=class="hlist hlist-separated"}}, which is a balanced tag pair; in the case of (ii), the {{tlx|startflatlist}} produces an unclosed {{tag|div|o|params=class="hlist hlist-separated"}} tag, and this is closed by the {{tlx|endflatlist}} which produces the balancing {{tag|div|c}} tag (and nothing else). Now Template:Startflatlist is merely a redirect to Template:Flatlist, so the second example may be written {{flatlist}}

and this shows that when {{tlx|flatlist}} is used without parameters, some form of explicit closure is required, which is why there is that {{tag|div|c}} after the {{tag|noinclude|o}}. --Redrose64 🌹 (talk) 10:04, 29 December 2020 (UTC)

Protected edit request on 3 June 2025

Please replace the live template with the sandbox version. This change does two things:

1. It moves the closing /div tag outside of the #if statement to match the opening div tag. This fixes an unclosed div tag error when the template is used with no input. See the relevant test case.

2. It adds standard template unknown parameter checking. There are currently 300+ pages using this template with unknown parameters, which is preventing desired information from being displayed. I just [https://en.wikipedia.org/w/index.php?title=Huawei_Mediapad_M5&diff=1293817387&oldid=1288427562 fixed an article] that previously had an incorrect fix applied because this template was not displaying any error messages.

Thanks! – Jonesey95 (talk) 21:25, 3 June 2025 (UTC)

:{{not done}}: I am fairly certain your change would break the use of flatlist to start a flatlist, as in a pair of {{flatlist}} * A * B * C{{endflatlist}}, no? Izno (talk) 22:01, 3 June 2025 (UTC)

::Ah, you are correct. I don't recall seeing that construction. I have modified the sandbox to implement only the parameter checking. – Jonesey95 (talk) 00:38, 4 June 2025 (UTC)

::: {{Done}} * Pppery * _{it has begun...} 01:04, 4 June 2025 (UTC)

::Should the template be usable is two ways like that? Would it not be better to have something like {{Tld|startflatlist}} for such cases? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:50, 6 June 2025 (UTC)

:::I think so, but that ship might have sailed. I don't know if it's worth the candle. – Jonesey95 (talk) 15:13, 6 June 2025 (UTC)
