[TW5] Resuseable person field drop-down list

[Matthew Petty]

I have tiddlers tagged "person", and a subset of those tagged "family". I want to create a drop-down list of the family people which would set the field "person" of the current tiddler to the title of the person tiddler.
That's easy to do once:

<$select field="person" default="">
<$list filter="[tag[person]tag[family]]">
<option>{{!!title}}</option>
</$list>
</$select>

It would be very nice to be able to put the above in a separate tiddler, called "Family Dropdown", and then transclude that whenever I need it (I want it in multiple places).

But when I tried just copying the code to "Family Dropdown" and transcluding it, the only the person field of "Family Dropdown" was changed, not the field in the current tiddler.

How can I fix that?

use "template transclusion", like this:

{{||FamilyDropdown}}

This will transclude the content from FamilyDropdown, but use the current tiddler for the data context.  Thus, field references in FamilyDropdown will modify values in the current tiddler.  Q.E.D.

Note: the full transclusion syntax is: {{ContextTiddler||TemplateTiddler}}, where ContextTiddler is the source of the data, and TemplateTiddler is the source for the output format.  In the above example, {{||FamilyDropdown}}, omitting the ContextTiddler implies the current tiddler by default.

enjoy,
