app.vue

<template>
    <div class="control-section">
            <ejs-querybuilder id="querybuilder" ref="querybuilder" :dataSource="dataSource" :rule="importRules" enableNotCondition = true :fieldModel = "{allowFiltering: true, popupHeight: '500px'}" :operatorModel = "{allowFiltering: true, popupHeight: '400px'}" :valueModel = "{numericTextBoxModel:
