[TW5] <$list filter How to show empty list, if filter show less than two items?

[sini-Kit]

Hi I have a simple filter <$list filter="[tag[ListWidget]]"/>   I want this list show items only if they more than one. if there is no items in my list or only one item, filter must show empty list.

Hi,

Have a look at the list widget [1] "empty" parameter. ... But it only works for filters, that return no result. Hence the name "emptyMessage"

I'm confused a bit. 1 item is not empty. At least not for me? ... Your use case also raises some questions for me, which you didn't describe in the OP.

eg:

 - filter returns A -> should be empty
 - filter returns B -> should be empty
 - filter returns B and A -> should be shown. ... but how. Show A or B or Both? ... Is the order important?

- I have 3 tiddlers with tag ListWidget A, B, C my filter must show A, B, C

-  I have 2 tiddlers with tag ListWidget A, B my filter must show A, B

-  I have 1 tiddler with tag ListWidget A my filter must show "empty"

-  I have 0 tiddler with tag ListWidget  my filter must show "empty"

I try somethink like

<$list filter="[tag[TableOfContents]sort[title]nth[2]]">
<$list filter="[tag[TableOfContents]]"/>
</list>

but it don't work.

</list>   <- ... is there a typo

imo should be </$list> ...


for me this:

\define empty()
empty
\end

<$list filter="[tag[a]sort[title]nth[2]]" emptyMessage=<<empty>> >
  <$list filter="[tag[a]]"/>
</$list>

seems to work. I did use a macro for the empty message, because it has more possibilities.

have fun!

unfortunately it didn't solve my problem

I try to modify my pure css3dslider for external images

here is result of this slider https://design4shop.ru/heeg.html#boston_ego_lab

and here is the code of this slider https://design4shop.ru/heeg.html#3dslider

this slider shows little previews under photos, and if i have only ONE photo, this one under photo is not necessary.

So at the end of this code i try to write

 <$list filter="[is[current]tagging[]type[image/jpeg]sort[title]nth[2]]"><$list filter="[is[current]tagging[]type[image/jpeg]sort[title]]"> <label for={{!!title}} class="arrows_th" >  <img  src={{!!_canonical_uri}}  alt={{!!alt}}/>   </label> </$list></$list>

but this filter shows nothing. i think my problem with is[current]tagging[]......

  <$list filter="[is[current]tagging[]type[image/jpeg]sort[title]nth[2]]"><$list filter="[is[current]tagging[]type[image/jpeg]sort[title]]"> <label for={{!!title}} class="arrows_th" >  <img  src={{!!_canonical_uri}}  alt={{!!alt}}/>   </label> </$list></$list>

yes. I do think so too. The first <$list widget changes the currentTiddler, which the second <$list is[current] tries to use again. .. just a guess. no testing done.

You may use the list-widget: variable   attribute. in the first list.
eg: <$list filter="[is[current]tagging[]type[image/jpeg]sort[title]nth[2]]" variable=test>

As I wrote. Just a guess. ... But that's the way I'd start to search.
