Mention component is used to tag objects in a text.
import { Mention } from 'primereact/mention';
Mention is used as a controlled component with value and onChange properties. In addition, suggestions and a onSearch are required to query the results.
<Mention value={value} onChange={(e) => setValue(e.target.value)} suggestions={suggestions} onSearch={onSearch} field="nickname"
placeholder="Enter @ to mention people" rows={5} cols={40} itemTemplate={itemTemplate} />
It is used to define the expected keyword/s in the input field to mention someone or something.
<Mention value={value} onChange={(e) => setValue(e.target.value)} trigger={['@', '#']} suggestions={multipleSuggestions} onSearch={onMultipleSearch}
field={['nickname']} placeholder="Enter @ to mention people, # to mention tag" itemTemplate={multipleItemTemplate} rows={5} cols={40} />
When autoResize is enabled, textarea grows instead of displaying a scrollbar.
<Mention value={value} onChange={(e) => setValue(e.target.value)} suggestions={suggestions} onSearch={onSearch} field="nickname"
placeholder="Enter @ to mention people" rows={5} cols={40} itemTemplate={itemTemplate} autoResize />
A floating label appears on top of the input field when focused.
<span className="p-float-label">
<Mention inputId="newpost" value={value} onChange={(e) => setValue(e.target.value)} suggestions={suggestions} onSearch={onSearch}
field="nickname" rows={5} cols={40} itemTemplate={itemTemplate} />
<label htmlFor="newpost">New Post</label>
</span>
Invalid state style is added using the p-invalid class to indicate a failed validation.
<Mention value={value} onChange={(e) => setValue(e.target.value)} suggestions={suggestions} onSearch={onSearch} field="nickname"
placeholder="Enter @ to mention people" rows={5} cols={40} itemTemplate={itemTemplate} inputClassName="p-invalid" />
When disabled is present, the element cannot be edited and focused.
<Mention disabled />
Value to describe the component can either be provided via label tag combined with inputId prop or using aria-labelledby, aria-label props. The input element has combobox role in addition to aria-autocomplete, aria-haspopup and aria-expanded attributes. The relation between the input and the popup is created with aria-controls and aria-activedescendant attribute is used to instruct screen reader which option to read during keyboard navigation within the popup list.
The popup list has an id that refers to the aria-controls attribute of the input element and uses listbox as the role. Each list item has option role and an id to match the aria-activedescendant of the input element.
<label htmlFor="men1">Username</label>
<Mention inputId="men1" />
<span id="men2">Email</span>
<Mention aria-labelledby="men2" />
<Mention aria-label="City" />
