<p>You can add an <code>input</code> tag with the name on it and hide the <code>name</code> property from the user. On the server, just use the <code>input</code> as the name and ignore the default name.</p>

<p>Spark 2.1.0 contains <code>com.fasterxml.jackson.core</code> as transitive dependency. So, we do not need to include then in <code>libraryDependencies</code>. </p> <p>But if you want to add a different <code>com.fasterxml.jackson.core</code> dependencies' version then you have to override them. Like this:</p> <pre...

How does StackOverflow's 'tags' textbox autocomplete work?
<p>I know they're using a jQuery plugin, but I can't seem to find which one they used. In particular, what I'm looking for is autocomplete with exactly the same functionality as SO's autocomplete, where it will perform an AJAX command with each new word typed in and allow you to select one from a dropdown.</p>
