All,
Just wanted to follow up on this since I appear to have stumbled across the
solution. My problem appears to have been the order in which I placed the
tag filter. I had noted:
"I thought I could fix this by adding "tag[$purchase]" to the first filter
> but doing so caused my list to completely disappear."
I mulled it over and decided to play around with that again. I found that
by placing it at the front of the filter I was able to get the results I
wanted, before I had placed it _*after*_ the aisle tags.
The following code worked for me:
<$list filter="[tag[$purchase]has[aisle]each[aisle]sort[aisle]]">
<div class="tw-menu-list-item">
<$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>
This dropped the "frozen" category from my list in the example.
Best regards,
mr
