title: How can I change the width of b-form-select
body: <p>I am using <code>b-form-select</code>, but by default it uses 100% width. How can I reduce the width? I tried something like that but that doesn't work.</p>
  <pre><code> &lt;b-form-select v-model=&quot;xxx&quot; :options=&quot;yyy&quot; width: 50%&gt;&lt;/b-form-select&gt;
  </code></pre>
