This thing is a modification to Ayano’s Comment Widget that allows you to lock specific comment threads.

To implement this to your site, here’s the steps:

1. Go to the Google Form you used to set up the widget, add a short-answer text question and name it ‘Locked’, wait a bit, then delete it. Yes, really.

   How does this work then?

   We don’t need the question to lock comments, we’re gonna do it on the google sheets. You can also verify that ‘Locked’ is on your Google Sheets for your comments, if there’s not, recreate it and delete it.

2. Now, we’re gonna edit some stuff on the forms. Find the displayComments() function on your script and find the // Main comments (not replies) comment. We’re gonna edit the loop below.
3. Find these codes:

    button.innerHTML = s_replyButtonText;
    button.value = comment.id;
    button.setAttribute('onclick', `openReply(this.value)`);
    button.className = 'c-replyButton';

4. We’re gonna replace them to this:

    button.disabled = Boolean(comments[i].Locked);
    button.innerHTML = button.disabled == true ? `Locked` : s_replyButtonText;
    if (!button.disabled) {
        button.value = comment.id;
        button.addEventListener('click', () => openReply(comment.id));
        button.className = 'c-replyButton';
    }

5. And you’re good to go! Try it by commenting, then pinning it on the sheets, by setting your comment’s Locked to TRUE! To have better protection against people replying on a locked thread, consider making a response validation to Reply! (use the comment’s ID for blocking it!)
