AMP: pre selected value in select box












0















What is the solution to have a pre selected value in the sample below? Let's say that the third option should be selected by default when data is retrieved from JSON and the select box is shown (without user interaction).



<script async src="https://cdn.ampproject.org/v0.js"></script>
<script async custom-element="amp-list" src="https://cdn.ampproject.org/v0/amp-list-0.1.js"></script>
<select>
<amp-list width="auto" height="100" layout="fixed-height" src="https://ampproject-b5f4c.firebaseapp.com/examples/data/amp-list-urls.json">
<template type="amp-mustache">
<option value="{{url}}">{{title}}</option>
</template>
</amp-list>
</select>

          There is a solution with "mustache inverted sections", but it does not work in my case due to other factors involved.



          I got it thanks to [Cathy Zhu][1], on [AMP Issues support page][2].



          I will provide it, in case it would be helpful for someone:



          <amp-selector>
          <amp-list width="auto" height="200"
          layout="fixed-height"
          src="//amp-list-selector.glitch.me/api/amp-list-data.json">
          <template type="amp-mustache">
          {{#selected}}
          // content displayed if selected is true
          <div class="story-entry" selected>
          <amp-img src="{{imageUrl}}" width="100" height="100"></amp-img>
          </div>
          {{/selected}}
          {{^selected}}
          // content displayed if selected is false
          <div class="story-entry">
          <amp-img src="{{imageUrl}}" width="100" height="100"></amp-img>
          </div>
          {{/selected}}
          </template>
          </amp-list>




          for the sample data:



          {


          "items": [
          {
          "title": "Cat",

          "selected": true
          },



          {

          "imageUrl": "https://lh3.googleusercontent.com/5rcQ32ml8E5ONp9f9-Rf78IofLb9QjS5_0mqsY1zEFc=w400-h300-no-n",

                There is a solution with "mustache inverted sections", but it does not work in my case due to other factors involved.



                I got it thanks to [Cathy Zhu][1], on [AMP Issues support page][2].



                I will provide it, in case it would be helpful for someone:



                <amp-selector>
                <amp-list width="auto" height="200"
                layout="fixed-height"
                src="//amp-list-selector.glitch.me/api/amp-list-data.json">
                <template type="amp-mustache">
                {{#selected}}
                // content displayed if selected is true
                <div class="story-entry" selected>
                <amp-img src="{{imageUrl}}" width="100" height="100"></amp-img>
                </div>
                {{/selected}}
                {{^selected}}
                // content displayed if selected is false
                <div class="story-entry">
                <amp-img src="{{imageUrl}}" width="100" height="100"></amp-img>
                </div>
                {{/selected}}
                </template>
                </amp-list>




                for the sample data:



                {


                "items": [
                {
                "title": "Cat",
                "imageUrl": "https://lh3.googleusercontent.com/pSECrJ82R7-AqeBCOEPGPM9iG9OEIQ_QXcbubWIOdkY=w400-h300-no-n",
                "selected": true
                },



                {
                "title": "Dog",
                "imageUrl": "https://lh3.googleusercontent.com/5rcQ32ml8E5ONp9f9-Rf78IofLb9QjS5_0mqsY1zEFc=w400-h300-no-n",
                "selected": false
                },
                {
                "title": "Mouse",
                "imageUrl": "https://lh3.googleusercontent.com/pSECrJ82R7-AqeBCOEPGPM9iG9OEIQ_QXcbubWIOdkY=w400-h300-no-n",

                }


                ]
                }
