Tag Select

Added in 9.1

Tag select is a JS alternative to <select> that allows you to create a nice looking multi-select with cross browser styling. Tag Select offers an API for creating interacting with the component.

Configuration and initialization

By default, Tag select will use the HTML markup to generate the data.

<div class="env-form-element">
   <label for="example-tag-select-1" class="env-form-element__label">Tag select</label>
   <div class="env-form-element__control">
      <select class="env-form-input" id="example-tag-select-1">
         <option value="">Select an item ...</option>
         <option value="item-1">Item</option>
         <option value="item-2">Item 2</option>
         <option value="item-3">Item 3</option>
         <option value="item-4">Item 4</option>

Initialize from script. You may pass any selector as a string, a DOM node or node list.

var tagSelect = envision.select('#example-tag-select-1');

Note: envision.select will return a Promise. Use the instance method .then() to access individual controls.

tagSelect.then(function (selects) {
   selects[0].addOptions({ value: 'newOption', text: 'New option' });

Options from JavaScript config

This example sets the options from the config. It will allow adding tags from the Tag Select itself, or from a separate input using the API.

<div class="env-form-element">
   <label for="example-tag-select-2" class="env-form-element__label">Advanced select</label>
   <div class="env-form-element__control">
      <input class="env-form-input" id="example-tag-select-2" />

<div class="env-form env-form--inline">
   <div class="env-form-element">
      <label for="country" class="env-form-element__label">Add tag using API</label>
      <div class="env-form-element__control">
         <input id="example-tag-select-2-tag" type="text" class="env-form-input" id="country" />
   <div class="env-form-element">
      <button id="example-tag-select-2-add" type="submit" class="env-button env-button--primary">
   .select('#example-tag-select-2', {
      maxItems: 5,
      placeholder: 'Select or add tags...',
      create: true, // Allow creating tags
      render: {
         item: (data, escape) =>
               <svg class="env-icon env-m-right--x-small"><use xlink:href="/sitevision/envision-icons.svg#icon-check-line"></use></svg>
      items: ['fruit01'], // Preselect one existing option
      options: [
         // Populate options
            value: 'fruit01',
            text: 'Apple',
            value: 'fruit02',
            text: 'Banana',
            value: 'fruit03',
            text: 'Grapefruit',
            value: 'fruit04',
            text: 'Lemon',
            value: 'fruit05',
            text: 'Pear',
      onOptionAdd: function (value, data) {
         // Event handler, runs when option is added
         console.log('Added:', value, data);
   .then((selects) => {
         .addEventListener('click', function () {
            var val = document.getElementById('example-tag-select-2-tag').value;
               value: val,
               text: val,

Options from remote data API

This example fetches repository names from github. It will preload some popular names on page load. The data does not follow the Tag Select naming standards so value-/label-/search-/sortField must be defined.

<div class="env-form-element">
   <label for="example-tag-select-3" class="env-form-element__label">Remote data</label>
   <div class="env-form-element__control">
      <input class="env-form-input" id="example-tag-select-3" />
envision.select('#example-tag-select-3', {
   maxItems: 5,
   placeholder: 'Select a Github repository...',
   i18n: 'en',
   valueField: 'url',
   labelField: 'name',
   searchField: ['name'],
   sortField: [{ field: 'name', direction: 'desc' }],
   preload: true,
   load: function (query, callback) {
      query = query || 'sitevision';
      var url =
         'https://api.github.com/search/repositories?q=' +
         .then((response) => response.json())
         .then((json) => {
         .catch(() => {



A Tag Select may be disabled by adding the disabled attribute in the HTML. When disabled, the control can not receive focus.

<div class="env-form-element">
   <label for="example-tag-select-4" class="env-form-element__label">
   <div class="env-form-element__control">
         class="env-form-input example-tag-select"
         <option value="">Select an item...</option>
         <option value="item1" selected>Item</option>
         <option value="item2">Item 2</option>


A Tag Select may be locked by adding the class env-select--locked to the <input> or <select>, or by using functions described in the API section.

Locked disables user input on the control, but the control can still receive focus.

Note: The readonly attribute is not supported or relevant to the Tag Select component. An input with the readonly attribute will be locked.

<div class="env-form-element">
   <label for="example-tag-select-6" class="env-form-element__label">
   <div class="env-form-element__control">
         class="env-select--locked env-form-input example-tag-select"
         <option value="">Select an item...</option>
         <option value="item1" selected>Item</option>
         <option value="item2">Item 2</option>

<div class="env-form-element">
   <label for="example-tag-select-5" class="env-form-element__label">
      Locked (readonly)
   <div class="env-form-element__control">
         class="example-tag-select env-form-input"
         placeholder="Select an item..."

API functions

Instances of Tag Select may be controlled by the methods described below.

envision.select('#tag-select').then(function (selects) {
   selects[0].addOptions({ value: 'test' });


  • addOptions(data)

    • Adds an available option, or array of options. If it already exists, nothing will happen. Note: this does not refresh the options list dropdown (use refreshOptions() for that).
  • getOption(value)

    • Retrieves the dom element for the option identified by the given value.
  • updateOption(value, data)

    • Updates an option available for selection. If it is visible in the selected items or options dropdown, it will be re-rendered automatically.
  • removeOption(value)

    • Removes the option identified by the given value.
  • refreshOptions(triggerDropdown)

    • Refreshes the list of available options shown in the autocomplete dropdown menu.
  • load(query)

    • Invoked when new options should be loaded from the server. Called with the current query string.
  • open() since Sitevision 2022.11.1

    • Shows the autocomplete dropdown containing the available options.
  • close() since Sitevision 2022.11.1

    • Closes the autocomplete dropdown menu.
  • clear(silent) since Sitevision 2022.11.1

    • Resets / clears all selected items from the control. If silent is truthy, no change event will be fired on the original input.
  • clearOptions(clearFilter?) since Sitevision 2022.11.1

    • Removes all unselected options from the control. To clear selection options, call clear() before calling clearOptions().
  • clearFilter(option, value) since Sitevision 2022.11.1

    • Callback used by clearOptions() to decide whether or not an option should be removed. Return true to keep an option, false to remove


  • getItem(value)

    • Returns the dom element of the item matching the given value.
  • addItem(value, silent)

    • "Selects" an item. Adds it to the list at the current caret position. If silent is truthy, no change event will be fired on the original input.


  • getValue()

    • Returns the value of the control. If multiple items can be selected with a "select" input tag (e.g. <select multiple>), this returns an array. Otherwise, returns a string (separated by delimiter if "multiple").
  • setValue(value, silent)

    • Resets the selected items to the given value.
  • lock()

    • Disables user input on the control. The control can still receive focus.
  • unlock()
