/**
`iron-selector` is an element which can be used to manage a list of elements
that can be selected. Tapping on the item will make the item selected. The `selected` indicates
which item is being selected. The default is to use the index of the item.
Example:
<iron-selector selected="0">
<div>Item 1</div>
<div>Item 2</div>
<div>Item 3</div>
</iron-selector>
If you want to use the attribute value of an element for `selected` instead of the index,
set `attrForSelected` to the name of the attribute. For example, if you want to select item by
`name`, set `attrForSelected` to `name`.
Example:
<iron-selector attr-for-selected="name" selected="foo">
<div name="foo">Foo</div>
<div name="bar">Bar</div>
<div name="zot">Zot</div>
</iron-selector>
You can specify a default fallback with `fallbackSelection` in case the `selected` attribute does
not match the `attrForSelected` attribute of any elements.
Example:
<iron-selector attr-for-selected="name" selected="non-existing"
fallback-selection="default">
<div name="foo">Foo</div>
<div name="bar">Bar</div>
<div name="default">Default</div>
</iron-selector>
Note: When the selector is multi, the selection will set to `fallbackSelection` iff
the number of matching elements is zero.
`iron-selector` is not styled. Use the `iron-selected` CSS class to style the selected element.
Example:
<style>
.iron-selected {
background: #eee;
}
</style>
...
<iron-selector selected="0">
<div>Item 1</div>
<div>Item 2</div>
<div>Item 3</div>
</iron-selector>
