<p dir="auto">I'm wondering if you can add a new feature: show nested menu when hover on item.<br>
I read your source code and found that the new menu was rendered on body. I don't know how to change code so the menu item can support this feature.</p>
<p dir="auto">the circle around the selected date in the calendar is down and left of where it should be to be centered with the selected number.</p>
<p dir="auto">this is verified on mac osx in chrome, safari, and firefox</p>
<p dir="auto">the circle should be:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="top: -7px;
left: 3px"><pre class="notranslate"><code class="notranslate">top: -7px;
left: 3px
</code></pre></div>
