I want to build Polymer element that generates a list output
<polymer-element name="polymer-list>
<template>
<template id="my-repeat" repeat="{{item in listData}}">
<!-- use content here -->
<!-- some fix dummy content to see how this is handled -->
<div id="div_{{item['item']['index']}}">{{item['item']['index']}}</div>
</template>
<content id="content" select="*"></content>
</template>
<script type="application/dart" src="polymer_list.dart"></script>
</polymer-element>
and I want to move the elements provided by <content select="*"></content> inside the <template id="my-repeat"> tag (at the position of <!-- use content here -->) when the polymer-list is initiated (ready, attached, ...).
My polymer-list should be used like
<polymer-list id="list" data="{{data}}" on-polymer-select="{{selectAction}}">
<div class="header">{{item['index']}}</div>
<div class="item {{item['selected']}}">Index: {{item['index']}}</div>
</polymer-list>
As result both <div>s should be repeated for each item in data by the <polymer-list> element.
I tried
var listContent = ($['content'] as ContentElement).getDistributedNodes();
var t = ($['my-repeat'] as TemplateElement);
listContent.forEach((n) => t.append(n.clone(true));
// listContent.forEach((n) => t.content.append(n.clone(true)); // didn't work either
as result I get
<!-- ... -->
<template id="my-repeat" repeat="{{item in listData}}">
#document-fragment
<div class="header"></div>
<div class="item">Index: </div>
</template>
<div id="div_0">0</div>
<div id="div_1">1</div>
<div id="div_0">2</div>
<!-- ... -->
The fix dummy content is repeated normally but the dynamically added elements are placed inside a document-fragment but not repeated.
Any hint about manipulating the HTML at <!-- use content here --> at runtime would be great.
