<section id="moduledoc">
<p>Phoenix LiveComponent for a combobox UI element with search and selection
functionality.</p><p>The component allows users to select an option from a list of options,
which can be searched by typing in the input field.</p><p>The component renders an input field with a dropdown anchor and a
hidden input field for submitting the selected value.</p><p>The number of options displayed in the dropdown is limited to 15
by default but can be customized. When a user types into the input
field, the component searches the available options and provides
suggestions based on the input.</p><p>Any function can be supplied via <code class="inline">suggest_fun</code> attribute</p><ul><li>see the provided <code class="inline">ComboBox.StaticSearch</code>.</li></ul><p>In most cases the <code class="inline">suggest_fun</code> runs an operation that could be deferred,
so by default, the <code class="inline">async={true}</code> attr calls it in a background Task
and updates the suggestions asynchronously. This way, you can render
the component without having to wait for suggestions to load.</p><p>If you explicitly need to make the operation synchronous, you may
pass <code class="inline">async={false}</code> option.</p><p>If your initial <code class="inline">options</code> are not provided up-front at initial render,
lack of <code class="inline">options</code> attr value combined with <code class="inline">async=true</code> calls the
<code class="inline">suggest_fun.(&quot;&quot;, [])</code> asynchronously - that special clause can be used
to provide the initial set of suggestions updated right after the initial render.</p><p>To simplify integration testing, suggestions load up synchronously during
tests. This lets you skip waiting for suggestions messages
to arrive. The asynchronous behaviour alone is already tested in
ComboBox own test suite, so there is no need for additional
verification.</p>
