Implementing the "Select All" Checkbox Functionality in HTML

A common challenge in HTML development is enabling multiple checkboxes to be selected simultaneously by using a "Select All" checkbox. This functionality allows users to conveniently toggle the state of all checkboxes efficiently.

To implement the "Select All" checkbox, a JavaScript function can be employed. The function should iterate through all checkboxes and set their checked property to the value of the "Select All" checkbox. Here's a code snippet demonstrating this approach:

To integrate this functionality into your HTML, add an additional checkbox labeled "Toggle All" or "Select All" with an onClick event handler that calls the toggle() function. For each checkbox that should be affected, assign the same name (e.g., "foo") to its name attribute.

By following these steps, you can add the "Select All" checkbox functionality to your HTML page, enhancing user experience and simplifying the selection process.
