Thank you Jeremy. Your macros is working, but I don't know how to modify it
to my proposes (I try many variants)
my idea was to make a list of checkboxes,
<$list filter="[is[current]tagging[]tag[$:/Note]each[vendor]get[vendor]]"
variable="vendor">
<$checkbox tiddler="$:/_allvendors" field= <<vendor>> checked="yes" > ''<<
vendor>>'' </$checkbox><br>
</$list>
the position of checkboxes I save in $:/_allvendors tiddler in its fields.
so, If the checkbox of vendor Dell is checked (unchecked), I want o remove
from list all tiddlers with field vendor="Dell'
<$list
filter="[is[current]tagging[]tag[$:/Note]!vendor[Dell]sort[stoimost]]"/>
if I check (uncheck) "Nikon" the list must look like <$list
filter="[is[current]tagging[]tag[$:/Note]!vendor[Dell]!vendor[Nikon]sort[stoimost]]"/>
so I want to create filter modifying by the lists of checkboxes .
but I can't understand, how to put many $fieldname$ into my list.
