Tag manager like interface for user fields

[LordEcthelion]

I am attempting to copy the $:/TagManager tiddler and tweak it to work for user defined fields instead.

I was able to hack my way through to get a table of all fields but I am not able to understand how to

• Get the accurate count of tiddlers which have that field (just like TagManager)
  
• A clickable list of all tiddlers which have that field (just like TagManager)

I am not sure if this is even achievable. Has anyone tried it and got it to work?

Here is the way, which is most likely incorrect, by which I was able to get the list of fields shown.

<table class="tc-tag-manager-table">
<tbody>
<tr>
<th class="tc-tag-manager-tag">Component</th>
<th>Count</th>
</tr>
<$list filter="[each[component]get[component]!is[system]sort[]]">
<tr>
<td>{{||$:/nikhil/FieldTemplate}}</td>
<td><$count filter="[all[current|tagging[]]]"/></td>
</tr>
</$list>
</tbody>
</table>
