    Description copied from corresponding location in WebComponent:

    <vaadin-select> is a Web Component for selecting values from a list of items. The content of the the select can be populated in two ways: imperatively by using renderer callback function and declaratively by using Polymer's Templates.

    Rendering

    By default, the select uses the content provided by using the renderer callback function.

    The renderer function provides root, select arguments. Generate DOM content, append it to the root element and control the state of the host element by accessing select.

    <vaadin-select id="select"></vaadin-select> const select = document.querySelector('#select');select.renderer = function(root, select) const listBox = document.createElement('vaadin-list-box'); // append 3 <vaadin-item> elements ['Jose', 'Manolo', 'Pedro'].forEach(function(name) { const item = document.createElement('vaadin-item'); item.textContent = name; listBox.appendChild(item); }); </p> <p> // update the content root.appendChild(listBox); ;}

    Renderer is called on initialization of new select and on its opening. DOM generated during the renderer call can be reused in the next renderer call and will be provided with the root argument. On first call it will be empty.

    Polymer Templates

    Alternatively, the content can be provided with Polymer's Template. Select finds the first child template and uses that in case renderer callback function is not provided. You can also set a custom template using the template property.

    <vaadin-select> <template> <vaadin-list-box> <vaadin-item label="foo">Foo</vaadin-item> <vaadin-item>Bar</vaadin-item> <vaadin-item>Baz</vaadin-item> </vaadin-list-box> </template> </vaadin-select>

    Hint: By setting the label property of inner vaadin-items you will be able to change the visual representation of the selected value in the input part.

    Styling

    The following shadow DOM parts are available for styling:

    Part name Description
    toggle-button The toggle button

    The following state attributes are available for styling:

    Attribute Description Part name
    opened Set when the select is open :host
    invalid Set when the element is invalid :host
    focused Set when the element is focused :host
    focus-ring Set when the element is keyboard focused :host
    readonly Set when the select is read only :host

    <vaadin-select> element sets these custom CSS properties:

    Property name Description Theme for element
    --vaadin-select-text-field-width Width of the select text field vaadin-select-overlay

    See ThemableMixin – how to apply styles for shadow parts

    In addition to <vaadin-select> itself, the following internal components are themable:

    • <vaadin-select-text-field>
    • <vaadin-select-overlay>

    Note: the theme attribute value set on <vaadin-select> is propagated to the internal themable components listed above.
