To get all tiddlers that has a "school" field, regardless of the value, you
would need to use the "has[school]" filter instead of
"school<!!schoolfilter>".
You can accomplish this by using a pair of <$reveal> widgets that uses the
{{!!school_filter}} input as the state:
<$reveal type="match" text="All" state="!!school_filter">
<$list filter="has[school]">
...
</$list>
</$reveal>
<$reveal type="nomatch" text="All" state="!!school_filter">
<$list filter="school{!!school_filter}">
...
</$list>
</$reveal>
