I have a question about taking this one step further, but first, I just
want to say thank you, thank you, thank you for this thread (original
poster and everyone who helped).
I was able to take this code and incorporate it into a grocery list that
I'd developed years ago and which I've been wanting to tweak. This code
allowed me to group my list by the aisle. (In actuality it's more like
general areas of the store.) It works great and I'm absolutely over the
moon about it as I had gone down many rabbit holes before I found what I
was looking for!
Now I'm wondering about tweaking it further so that it doesn't show the
name of an aisle when there are no items on the list for that particular
trip.
Let me 'splain:
I have dozens of tiddlers of various grocery items, each with a field
called "aisle" with values like "bakery", "dairy", "frozen", "meats." I
have a full list to choose from of potential grocery items and clicking an
item tags them with "$purchase" (meaning "to be purchased") and they move
to the current shopping list.
With help from this thread I developed the code below to show the current
shopping list grouped by aisle. As I shop, checking an item on that list
tags it as "$purchased" (not to be confused with "$purchase" above!) and
drops it from the list.
Here is the code:
<$list filter="[has[aisle]each[aisle]sort[aisle]]">
<div class="tw-menu-list-item">
<$view field="aisle"/>
</div>
<$list filter="[!tag[$purchased]tag[$purchase]aisle{!!aisle}sort[title]]">
<div class="tw-menu-list-subitem">
<$button class="tc-btn-invisible">
<input type="checkbox"/>
<$action-listops $tags="$purchased"/>
</$button> <$link to={{!!title}}><$view field="title"/></$link>
</div></$list></$list>
The above might produce a list something like this:
bakery
bread
cookies
dairy
milk
cream
frozen
meats
chicken
sausage
etc.
As you can see, there are items under the "aisle" headers for "bakery",
"dairy" and "meats"; but none under "frozen". What I want is, if there are
no items from the frozen aisle (aisle="frozen") tagged with "$purchase",
then suppress the header (in this case "frozen") from appearing on the
list. That is, only show the header for "aisles" that contain items tagged
with "$purchase".
I thought I could fix this by adding "tag[$purchase]" to the first filter
but doing so caused my list to completely disappear.
My skill level is pretty basic but improving. Is there an easy fix for
this? Am I missing something obvious?
Best regards and thank you for any help.
