<template> <DocSectionText v-bind="$attrs"> <p> More than one node is selectable by setting <i>selectionMode</i> to <i>multiple</i>. By default in multiple selection mode, metaKey press (e.g. <i>⌘</i>) is not necessary to add to existing selections. When the optional <i>metaKeySelection</i> is present, behavior is changed in a way that selecting a new node requires meta key to be present. Note that in touch enabled devices, TreeSelect always ignores metaKey. </p> <p>In multiple selection mode, value binding should be a key-value pair where key is the node key and value is a boolean to indicate selection.</p> </DocSectionText> <DocSectionCode :code="activeNodes" hideToggleCode importCode hideStackBlitz v-bind="$attrs" /> <div class="card flex justify-center"> <TreeSelect v-model="selectedValue" :options="nodes" selectionMode="multiple" display="chip" :maxSelectedLabels="3" placeholder="Select Items" class="md:w-80 w-full" /> </div> <DocSectionCode :code="code" :service="['NodeService']" v-bind="$attrs" /> </template> <script> import { NodeService } from '/service/NodeService'; export default { data() { return { nodes: null, selectedValue: null, activeNodes: { basic: ` { '0-0': true, '0-1-0': true } ` }, code: { basic: ` <TreeSelect v-model="selectedValue" :options="nodes" selectionMode="multiple" display="chip" :maxSelectedLabels="3" placeholder="Select Items" class="md:w-80 w-full" /> `, options: ` <template> <div class="card flex justify-center"> <TreeSelect v-model="selectedValue" :options="nodes" selectionMode="multiple" display="chip" :maxSelectedLabels="3" placeholder="Select Items" class="md:w-80 w-full" /> </div> </template> <script> import { NodeService } from './service/NodeService'; export default { data() { return { nodes: null, selectedValue: null, } }, mounted() { NodeService.getTreeNodes().then((data) => (this.nodes = data)); } } <\/script> `, composition: ` <template> <div class="card flex justify-center"> <TreeSelect v-model="selectedValue" :options="nodes" selectionMode="multiple" display="chip" :maxSelectedLabels="3" placeholder="Select Items" class="md:w-80 w-full" /> </div> </template> <script setup> import { ref, onMounted } from 'vue'; import { NodeService } from './service/NodeService'; const nodes = ref(null); const selectedValue = ref(null); onMounted(() => { NodeService.getTreeNodes().then((data) => (nodes.value = data)); }); <\/script> `, data: ` { key: '0', label: 'Documents', data: 'Documents Folder', icon: 'pi pi-fw pi-inbox', children: [ { key: '0-0', label: 'Work', data: 'Work Folder', icon: 'pi pi-fw pi-cog', children: [ { key: '0-0-0', label: 'Expenses.doc', icon: 'pi pi-fw pi-file', data: 'Expenses Document' }, { key: '0-0-1', label: 'Resume.doc', icon: 'pi pi-fw pi-file', data: 'Resume Document' } ] }, { key: '0-1', label: 'Home', data: 'Home Folder', icon: 'pi pi-fw pi-home', children: [{ key: '0-1-0', label: 'Invoices.txt', icon: 'pi pi-fw pi-file', data: 'Invoices for this month' }] } ] }, ...` } }; }, mounted() { NodeService.getTreeNodes().then((data) => (this.nodes = data)); } }; </script>
