title: Vue js multiselect - having custom suggestion text
body: <p>I am using <a href="https://github.com/monterail/vue-multiselect" rel="noreferrer">vue multiselect plugin</a> in my Vue v.1x project. I am wondering how can I customise suggestion text like <code>Press enter to select</code> or <code>Press enter to remove</code>, when hovering over options? 
  You can see the example in the <a href="https://jsfiddle.net/jqofkzxc/17/" rel="noreferrer">fiddle</a>. I have tried with setting the <code>:selectLabel="Select"</code> but that didn't work.</p>
