Search option in multi-select listbox document property
<p>I am trying to create a multi-select list box document property with unique values in a column. But, I don't see a search box feature like in the default list box property. </p>

<p>Please advise as how should I include this option in the list box document property that I created.</p>

<p>For the default listbox filter, we can choose if the search option to be included or not (as shown in the screenshot below). Don't we have this option available for document property?</p>

<p>Thanks for your help!</p>
