Setup

npm i @michael-brauner/choosy
yarn add @michael-brauner/choosy

import Choosy from "@michael-brauner/choosy";

new Choosy(document.getElementById("cars"));

<!-- import this inside of the `head` of your html document -->
<link rel="stylesheet" href="/dist/choosy.min.css">

<select name="cars" id="cars" multiple>
    <option value="volvo">Volvo</option>
    <option value="saab">Saab</option>
    <option value="mercedes">Mercedes</option>
    <option value="audi">Audi</option>
</select>

Be aware that Choosy automatically restricts the input limit to 1 as soon as the multiple attribute is not set onto the select element.

Options

Your choosy widget can be configured with some options.
Just pass your options object as second argument into the Choosy constructor.

After the widget got initialized the full Choosy object got stored inside a __x variable. This way you can access all public methods even after initialisation.

enabled

Enable or disable your Choosy.

This causes that no input is possible anymore, the widget is locked at the current state and can't be focused anymore. A greyed-out effect visualizes this behavior and the cursor shows not-allowed.

new Choosy(document.getElementById("cars_disabled"), {
    enabled: false
});

It is possible to enable / disable the whole widget after initialisation:

// enable the widget
getElementById("cars_disabled").__x.enable()

// disable the widget again
getElementById("cars_disabled").__x.disable()

limit

Limits the items you can select with your Choosy widget.

new Choosy(document.getElementById("cars_limited_2"), {
    limit: 2
})

Contributing

Since Choosy is an open-source project you are very welcome to contribute by sending a PR.

Compiling

To apply the latest changes and compile it to a ready-to-go package into the dist folder you can use the following commands:

postcss ./src/style/choosy.css -o ./dist/choosy.min.css
rollup -c 

Testing

Choosy uses Cypress for testing.
So you are able to start the testsuite with this command:

yarn tests 

If you want to use the cypress client to debug your tests in a real browser, you have to start the http-server first then you can open the cypress-suite:

yarn http-server -c-1 &
yarn cypress open

Actually you can use the test script for testing:

sh test

Don't forget to stop the server after you are done:

CTRL + c # to stop the cypress suite
fg # to bring the http-server in the foreground
CTRL + c # stop the http-server
