This template causes tiddlers to display the field(s) and value(s) and suppressing the display of system fields if the tiddler has the show-fields field. It has some problems like the show-field has to have something in the value to work and I can't seem to pass more than one field name to the filter. It is tagged $:/tags/ViewTemplate and uses a list filter that I don't understand. I got it mostly working but I want to be able to add or remove displayed fields by passing the field value of my show-field. Any suggestions? Here is my work in progress.

Hi Andrew

Here's a reworked version of your code:

\define body()

<$list filter="[is[current]fields[]sort[]] -draft.of -draft.title -show-field -text -title -modified $(showfield)$" variable="listItem">

</tr>

</$list>

\end

<$list filter="[all[current]has[show-field]]">

<tbody>

<$set name="showfield" value={{!!show-field}}>

<<body>>

</$set>

</tbody>

</table>

</$list>

The major changes were:

* Moving the body of the table into a macro so that the $()$ syntax works - textual substitutions only occur when macros are parsed

* Using the "has" filter operator to detect presence of a field

* Removing the double quotes around the "value" attribute of the set widget; they cause their content to be treated as a literal string, so that the {{}} syntax isn't parsed as a transclusion

* Using line-breaks to make the code a bit easier to read

Best wishes

Jeremy.

Thank you Jeremy. Your accuracy and precision were amazing. It is so well formed and works so well that I am realizing I need to spend some more time studying your work. And I am floored by how quickly you responded. Thank you.
