I noticed there were no "selectbox" widgets within the Paper Elements section of Polymer documentation, nor did I see one in the Polymer GitHub repos. Also I don't recall seeing any specific guidance on the Material Design specifications as to how a selectbox should look or behave.
Are there proposals out there? Or specific plans to incorporate designs for selectboxes within material design / polymer paper elements?
I definitely understand that you can basically get the same functionality from checkboxes (multi) or radio buttons (single), but from an aesthetic perspective, depending on the specific application, I get the feeling it may be a good idea to have 'select' available as an option.
You can use the paper-dropdown-menu, for example:
<paper-dropdown-menu label="Favorite fruit" name="fruit">
<paper-dropdown class="dropdown">
<core-menu class="menu">
<paper-item>apples</paper-item>
<paper-item>oranges</paper-item>
<paper-item>pears</paper-item>
</core-menu>
</paper-dropdown>
</paper-dropdown-menu>
