Package Exports

@voerro/vue-tagsinput

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@voerro/vue-tagsinput) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Vue Tags Input

A simple tags input with typeahead built with Vue.js 2.

Live Demo

Installation via NPM

npm i @voerro/vue-tagsinput --save-dev

npm i @voerro/vue-tagsinput --save

Then register the component with Vue:

import TagsInput from '@voerro/vue-tagsinput';

Vue.component('tags-input', TagsInput);

You might also need to add this line if removing tags by pressing backspace doesn't work (usually it works without the line):

Vue.config.keyCodes.backspace = 8;

Also read the Styling section to learn how to make the input look like in the live demo.

Usage

<tags-input element-id="tags"
    v-model="selectedTags"
    :existing-tags="{ 
        'web-development': 'Web Development',
        'php': 'PHP',
        'javascript': 'JavaScript',
    }"
    :typeahead="true"></tags-input>

<tags-input element-id="tags"
    v-model="selectedTags"
    :existing-tags="{ 
        1: 'Web Development',
        2: 'PHP',
        3: 'JavaScript',
    }"
    :typeahead="true"></tags-input>

element-id will be applied to id and name attributes of the hidden input that contains the list of the selected tags as its value. Optionally you can also use the v-model directive to bind a variable to the array of selected tags.

existing-tags is the list of the existing on your website tags. Include it even if you're not using typeahead.

Remove the typeahead property to disable this functionality.

"Old" Tags

If you need to display a list of already attached tags, use the :old-tags property. Provide an array of tag slugs, tag ids, or just strings.

<tags-input element-id="tags"
    :existing-tags="{ 
        'web-development': 'Web Development',
        'php': 'PHP',
        'javascript': 'JavaScript',
    }"
    :old-tags="[
        'php',
        'javascript',
    ]"
    :typeahead="true"></tags-input>

In this Laravel example we attach either the tags from old(), the tags of an existing blog post, or nothing, depending on what's available.

<tags-input element-id="tags"
    :existing-tags="{ 
        'web-development': 'Web Development',
        'php': 'PHP',
        'javascript': 'JavaScript',
    }"
    :old-tags="{{ 
        old('tags') ? json_encode(old('tags')) :
        (
            isset($postTags)
            ? json_encode($postTags)
            : json_encode('')
        ) 
    }}"
    :typeahead="true"></tags-input>

Data

The list of selected tags is stored as a string (tags separated with a comma) inside a hidden input with id and name set to the value from the element-id props (but only if you've provided this prop).

You can also bind the array of selected tags to a variable via v-model.

If a tag is listed in existing-tags, the tag's slug will be used, otherwise the text entered by user is added.

Example value of the hidden input:

web-development,javascript,This is a new tag,php

Styling

To apply styling include the dist/style.css file on your page. Copy and edit the file if you want to modify the package's appearance. If you're using Bootstrap 4 you can delete the .badge* classes as they were copied from the default Bootstrap 4's css.

You can apply a wrapper class to make the input look different via the input-class prop. input-class="form-control" if you're working with bootstrap, input-class="input" if you're working with Bulma, or input-class="your-custom-class" if you have something else.

Typeahead

When search results are displayed underneath the input, use the arrow down and arrow up keys on the keyboard to move the selection. Press Enter to select a tag. Press Esc to discard the search results and then Enter to add a new tag the way you've typed it.
