vue-taggable-select2

A Vue component that makes long, unwieldy select boxes user friendly.

Check out a demo here

Note

This component has been forked from vue-taggable-select as it has gone cold and I had some issues that needing fixing

What it Does

vue-taggable-select2 provides an elegant, user-friendly component to replace long, unwieldy multi select elements. Great for users. Simple for developers.

Simple API

<vue-taggable-select2 :taggable="true" v-model="sport" :options="['baseball','football','basketball','hocke']"></vue-taggable-select2>

What It Does Not Do

Currently, does not provide a simple select component (but we are planning to implement). In the meantime, try out this component!

Vue Single Select

No ajax loading.

Usage

        },
    })
</script>

Install Via NPM

Register it

In your component:

import VueTaggableSelect2 from "vue-taggable-select2"
export default {
    components: {
        VueTaggableSelect2,
    },
    //...
}

Globally:

import VueTaggableSelect2 from "vue-taggable-select2"
Vue.component("vue-taggable-select2", VueTaggableSelect2)

Use It

<vue-taggable-select2 make-it-taggable="good!" :taggable="true" v-model="sport" :options="['baseball','football','basketball','hockey']" :required="true"></vue-taggable-select2>

Use It Again

<vue-taggable-select2
    name="maybe"
    placeholder="pick a post"
    you-want-to-select-a-post="ok"
    v-model="post"
    out-of-all-these-posts="makes sense"
    :options="posts"
    a-post-has-an-id="good for search and display"
    option-key="id"
    the-post-has-a-title="make sure to show these"
    option-label="title"
></vue-taggable-select2>

Use It Again

<vue-taggable-select2
    you-want-to-select-a-reply="yes"
    v-model="reply"
    out-of-all-these-replies="yep"
    :options="replies"
    a-reply-only-has-a-reply="sounds about right"
    option-label="reply"
    seed-an-initial-value="what's seed mean?"
    initial="seed me"
    you-only-want-20-options-to-show="is 20 enough?"
    :max-results="20"
></vue-taggable-select2>

Dont like the Styling?

You can override some of it. Like so:

<vue-taggable-select2
    id="selected-reply"
    name="a_reply"
    option-label="reply"
    v-model="reply"
    :options="replies"
    you-like-huge-dropdowns="1000px is long!"
    max-height="1000px"
    :classes='{
            icons: "icons"
            active: "active",
            wrapper: "multi-select-wrapper",
            searchWrapper: "search-wrapper",
            searchInput: "search-input",
            pill: "pill",
            required: "required",
            dropdown: "dropdown"
        }'
></vue-taggable-select2>

Then all you need to do is provide some class definitions like so:

.active {
    background-color: pink;
}
.multi-select-wrapper {
    display: block;
    font-size: 16px;
}
.search-input {
    color: black;
}
.pill {
    padding: 0.5em;
}

... and so on.

Note: Bootstrap 3 Users May want to increase the size of the icons.

If so do this:

.icons svg {
    height: 1em;
    width: 1em;
}

Why vue-taggable-select2 is better

1. It handles custom label/value props for displaying options.

   Other select components require you to conform to their format. Which often means data wrangling.

2. It's easier on the DOM.

   Other components will load up all the options available in the select element. This can be heavy. vue-taggable-select2 makes an executive decision that you probably will not want to scroll more than N options before you want to narrow things down a bit. You can change this, but the default is 30.

3. Snappy Event Handling

   • up and down arrows for selecting options
   • enter to select first match
   • remembers selection on change
   • hit the escape key to, well, escape
   • hit delete to remove the last selection

4. Lightweight

   • Why are the other packages so big and actually have dependencies?

5. It works for regular 'POST backs' to the server.

   If you are doing a regular post or just gathering the form data you don't need to do anything extra to provide a name and value for the selected option.

    // This corresponds to v-model
