I am new to WAB and widgets. Could you clarify why html starts with "nls". ${nls.fields}, ${nls.add} etc
also how I can understand which class to use where e.g.
<td>
<div data-dojo-attach-point="btnAdd" data-dojo-type="dijit/form/DropDownButton">
<span>${nls.add}</span>
<div data-dojo-type="dijit/TooltipDialog">
<div data-dojo-attach-point="menu" data-dojo-type="dijit/Menu"></div>
</div>
</div>
</td>
your help is greatly appreciated!
