Creating Snap Lists

You can create a snap list component with the marquee component using the SnapListview API and the helper script.

This feature is supported in wearable applications only.

The following figure shows the layout of the list component in a rectangular and circular UI.

To implement the list component, follow these steps:

  1. Edit the HTML code to add the list component to your application screen:

    <div class="ui-page ui-page-active" id="snapListPage">
   <header class="ui-header">
      <h2 class="ui-title">Snap List</h2>
   </header>
   <div class="ui-content">
      <ul class="ui-listview ui-snap-listview expand-list" id="snapList">
         <li class="li-has-3line">
         <div class="ui-marquee ui-marquee-gradient">1.3line SnapListview with Marquee SnapListview with Marquee</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
         </li>
         <li class="li-has-3line">
            <div class="ui-marquee ui-marquee-gradient">2.3line SnapListview with Marquee SnapListview with Marquee</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
         </li>
         <li class="li-has-3line">
            <div class="ui-marquee ui-marquee-gradient">3.3line SnapListview with Marquee SnapListview with Marquee</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
         </li>
         <li class="li-has-3line">
            <div class="ui-marquee ui-marquee-gradient">4.3line SnapListview with Marquee SnapListview with Marquee</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
         </li>
         <li class="li-has-3line">
            <div class="ui-marquee ui-marquee-gradient">5.3line SnapListview with Marquee SnapListview with Marquee</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
            <div class="li-text-sub ui-li-sub-text">sub-text</div>
         </li>
      </ul>
   </div>
</div>

  2. Edit the CSS code to set the visual style of the list:

    .ui-listview li .li-text-sub {
   display: block;
   text-overflow: ellipsis;
   overflow: hidden;
   line-height: 32px;
   color: rgb(51, 51, 51);
}

.ui-listview li.li-has-3line {
   padding-top: 0;
   padding-bottom: 0;
   height: 115px;
}

.ui-listview.expand-list li.li-has-3line .ui-marquee {
   -webkit-transform: translate3d(0, 30px, 0);
}

.ui-listview.expand-list li.li-has-3line.ui-snap-listview-selected .ui-marquee {
   -webkit-transform: translate3d(0, 0, 0);
   -webkit-transition: all ease 1s;
}

.ui-listview.expand-list li.li-has-3line .ui-li-sub-text:nth-child(2) {
   -webkit-transform: translate3d(0, -10px, 0);
   opacity: 0;
}

.ui-listview.expand-list li.li-has-3line.ui-snap-listview-selected .ui-li-sub-text:nth-child(2) {
   -webkit-transform: translate3d(0, 0, 0);
   opacity: 1;
   -webkit-transition: all ease 1s;
}

.ui-listview.expand-list li.li-has-3line .ui-li-sub-text:last-child {
   -webkit-transform: translate3d(0, -42px, 0);
   opacity: 0;
}

.ui-listview.expand-list li.li-has-3line.ui-snap-listview-selected .ui-li-sub-text:last-child {
   -webkit-transform: translate3d(0, 0, 0);
   opacity: 1;
   -webkit-transition: all ease 1s;
}

  3. Edit the JavaScript code to manage the list events and other functionality:

    var page = document.querySelector('#snapListPage'),
    listHelper;

page.addEventListener('pagebeforeshow', function() {
    var list = document.getElementById('snapList');

    if (tau.support.shape.circle) {
        listHelper = tau.helper.SnapListMarqueeStyle.create(list, {marqueeDelay: 1000});
    }
});

page.addEventListener('pagehide', function() {
    if (tau.support.shape.circle) {
        if (listHelper) {
            listHelper.destroy();
        }
    }
});
