<p><strong>NOTE</strong>: that the <code class="highlighter-rouge">listkey</code> and <code class="highlighter-rouge">listvalue</code> attribute will default to <code class="highlighter-rouge">key</code> and <code class="highlighter-rouge">value</code> respectively only when
the <code class="highlighter-rouge">list</code> attribute is evaluated to a Map or its descendant. Everything else will result in <code class="highlighter-rouge">listkey</code> and <code class="highlighter-rouge">listvalue</code>
to be null and not used.</p>

form is submitted, its elements will be submitted in the order they are arranged (top to bottom).</p>
