Paper-input: Suggest Values In Typeahead

Is there an easy way to implement a typeahead using Polymer's element? The HTML

Solution 1:

Besides the fact you misuse options,

<datalist id="dl">
  <option value='a'></option>
  <!-- WRONG: <option>a</option> -->
</datalist>

I would suggest you to take a look into paper-input code and use paper-input-decorator with plain input as they do for paper-input:

<paper-input-decorator id="decorator">
  <input list="dl" is="core-input">
  <datalist id="dl">
    <option value='a'></option>
    <option value='ab'></option>
    <option value='ac'></option>
    <option value='ffa'></option>
  </datalist>
</paper-input-decorator>

Solution 2:

Polymer/paper-input has been deprecated, the currently supported version is PolymerElements/paper-input.

To use a datalist with paper-input in Polymer 1.0+:

<paper-input-container>
    <input list="choices" is="iron-input">
    <datalist id="choices">
        <option value='a'></option>
        <option value='ab'></option>
        <option value='ac'></option>
        <option value='ffa'></option>
    </datalist>
</paper-input-container>

Solution 3:

Vaadin Combo Box https://vaadin.com/elements/-/element/vaadin-combo-box is a good apache-2 licensed option for a typeahead that fits in with the paper elements.

Solution 4:

Checkout this element. It's an element has the typeahead function.
