Best Practices

• Use the Fluid component as a wrapper for bulk application of full-width styles to inputs instead of adding the fluid prop to every individual field for cleaner and more maintainable templates source

<Fluid>
    <div class="grid grid-cols-2 gap-4">
        <InputText placeholder="Full Width" />
        <DatePicker placeholder="Full Width" />
        <Select placeholder="Full Width" />
    </div>
</Fluid>

• In Stepper vertical layouts, always wrap Step and StepPanel inside a StepItem component to ensure correct structure and connection between headers and content source

• Use asChild and v-slot on components like Step or Tab to implement headless mode for full UI control while retaining PrimeVue's built-in accessibility logic source

<Step v-slot="{ activateCallback, value, a11yAttrs }" asChild :value="1">
    <button @click="activateCallback" v-bind="a11yAttrs.header">
        Step {{ value }}
    </button>
</Step>

• For performant row expansion in DataTable with large datasets, use an object for expandedRows combined with dataKey instead of an array of row objects source

// Preferred (O(1) lookup)
const expandedRows = ref({ '1004': true, '1005': true });

// In template
<DataTable v-model:expandedRows="expandedRows" dataKey="id">

• Enable automatic user preference persistence (sorting, filtering, paging) in DataTable using stateStorage and stateKey to improve UX across page visits source

• Add a delay to VirtualScroller to throttle rendering during rapid scrolling, significantly improving UI responsiveness for extremely large lists source

<VirtualScroller :items="items" :itemSize="50" :delay="250">
    <template v-slot:item="{ item }">{{ item }}</template>
</VirtualScroller>

• Implement semantic navigation menus by using Tabs without TabPanels and combining it with router-link for accessible, state-aware top or side bars source

• Always wrap inputs and icons with IconField and InputIcon to ensure correct positioning and styling, supporting both leading and trailing icon placements source

<IconField>
    <InputIcon class="pi pi-search" />
    <InputText placeholder="Search" />
</IconField>

• Use IftaLabel for modern, top-aligned in-field labels that visually integrate with the input and handle validation states automatically source

• Leverage the built-in DataTable context menu integration to provide row-specific actions without manual event listener management or custom positioning logic source

<ContextMenu ref="cm" :model="menuModel" />
<DataTable :value="products" contextMenu @row-contextmenu="onRowContextMenu">
