I have a paper-select element that I want to customize with a default value when the page loads or after a specific event occurs.
<dom-module id="custom-paper-select">
<template>
<paper-select id="select-input-1"
multiple
label-field="name"
bind-value="{{dataBind}}"
on-input-changed="interestsChanged"
nonmatching on-adding-item="addItem" select-on-blur
label="Choose your preferred programming language"
placeholder="Select an item"
value="df"
autofocus
>
</paper-select>
</template>
