How to set 100% height on polymer core-list in paper-tabs

Question

I'm trying to make 100% height on core-list element placed in <paper-tabs> in polymer. Unfortunately when I'm tryng to solve my problem with comment from this link StackOverflow Height on Core-list my core list gets 80px height and I'm not able to set height bigger value.

My code below:

<polymer-element name="progress-page" attributes="hash">
    <template>
        <link rel="stylesheet" href="../assets/css/styles.css">
        <link rel="stylesheet" href="../assets/css/menu-card.css">
    <sidebar-layout selected="main-page">
        <div class="title">Report</div>
        <div class="page-holder" horizontal layout center center-justified>
            <div class="page-sub-title">Progress</div>
        </div>


        <paper-tabs selected="{{selected}}">
            <paper-tab>Tab 1</paper-tab>
            <paper-tab>Tab 2</paper-tab>
        </paper-tabs>

        <core-pages  selected="{{selected}}">
            <div>
                <div class="content" fit style="overflow:auto;">
                    <core-list data="{{data}}" fit height="120" style=" height: 100%;">
                        <template>
                            <div class="row" layout horizontal center>
                                <div data-index="{{index}}">{{model.name}}</div>
                            </div>
                        </template>
                    </core-list>
                </div>
             </div>

                <div>
                    Page 2 qasdasd
                </div>
        </core-pages>


    </sidebar-layout>


</template>

<script>
    Polymer('progress-page', {
        ready: function () {
            this.selected = 0;
            this.data = generateContacts();

            function generateContacts() {
                var data = [];
                for (var i = 0; i < 1000; i++) {
                    data.push({
                        name: 'dddd',
                        string: 'asd'
                    });
                }
                return data;
            };
        }
    });
</script>

Answer 1

Your core-list fit to it's parent element which is a selected page with div element under core pages. Make sure you set the right size to it's parent.
