How to implement multiple input checkbox in vanilla JavaScript?

We will learn how to implement multiple input checkbox. The checkbox input selector will have the following functionalities ?

• Multiple options can be selected using the checkbox.

• Chosen options will be displayed as a separate list.

• Delete icon will be provided against each chosen option to uncheck / delete that option.

Another thing to note is that we will not be using any third-party library to achieve these functionalities and everything will be written in HTML + JavaScript + CSS only.

Approach

• We will have an object whose key will be used as the label for checkbox input and value (true/false) will be used as checked property.

• We will then render each key of that object.

• And every time the status of any option changes we will re-render the list.

• And similarly, on click of the delete icon, we will update options and re-render the list.

Example

Therefore, let's have a look at the code for the same ?

Explanation

• The above code creates a webpage that displays a set of checkboxes.

• Each with a different color label (Red, Green, Yellow, etc.).

• When a checkbox is selected, the corresponding color label is displayed in the "holder" div at the top of the page.

• The label also appears with an "x" that, when clicked, deselects the checkbox and removes the label from the "holder" div.

• The code uses JavaScript to manipulate the DOM and handle the checkbox selections and deselections.
