Amp dropdown with other option

I have drop down of some choice where last option is "Other".

I want to display text field when user select other option from drop down.

I am using normal html, Sorry I am AMP beginner, I found some example of amp-list with json option, but i don't know how to implement as i have limited options in drowpdown. 

<select data-type="text" id="cuisine" name="cuisine" required>
    <option value="german">German wine</option>     
    <option value="baden">Baden cuisine</option>
    <option value="hamburg">Hamburg cuisine</option>
    <option value="others">Others</option>
<select>
<div class="form-group hide" id="other_cusone">
    <label for="other_city_p" class="active">Other :</label>
    <input type="text" id="other_c_p" name="other" placeholder="Other"> 
</div>

thanks

Solution

  • For limited option you don't have to use amp-list, it is for dynamic dropdown. you can achieve your goal by using amp-bind.

    Here is working url

    Code: 

    <!doctype html>
<html ⚡>
<head>
  <meta charset="utf-8">
  <title> AMP amp-bind </title>
  <script async src="https://cdn.ampproject.org/v0.js"></script>
  <script async custom-element="amp-bind" src="https://cdn.ampproject.org/v0/amp-bind-0.1.js"></script>

 <select on="change:AMP.setState({ option: event.value })" data-type="text" id="cuisine" name="cuisine" required>

<div  hidden [hidden]="option != 'others'" class="form-group hide" id="other_cusone">
