the dom-repeat element offers filter attribute. is there similar way filter iron-list ? for example: given list of people, want filter ones born in specific city. as iron-list unfortunately doesn't offer filter attribute, there no declarative pattern making possible. you can either implement own simple list element making use of dom-repeat 's filter property. (with element inheritance coming in future releases, might extend iron-list ). however, best practice see use of computed property: <template> <iron-list items="[[filteritems(items)]]" as="item"> ... </iron-list> </template> <script> polymer({ ... filteritems: function (items) { return items.filter(function (item) { // array.prototype.filter return item.priority > 8; // filter condition }); } }); </script>
