handlebars.js – 如何在胡子模板中添加注释？

在我的Mustache模板中,我想评论几行,但我无法做到.我仍然在 HTML中显示评论.添加评论的正确方法是什么？有人可以帮我解决这个问题吗？

这是我的代码：

<script type="text/html" id="inspector-splitViewBase">
    <div class="inspector-split-view-container flex-1 flex-fill flex-down">
        <header class='split-view-inspector-header'>
            <div class="view-title">source Assets</div>
            {{!--  <div class="actions"> commented 
                <span class="label">Actions</span>
                <span class="gear"></span>
            </div> --}} - comment is not working
        </header>
        <div class='search-container'>
            <span class="search-icon"></span>
            <input type="text" value="" class="inspector-search" />
        </div>
        <div class="source-assets-list-container flex-1"></div>
        <footer></footer>
    </div>
</script>

Comments begin with a bang and are ignored. The following template:
    <h1>Today{{! ignore me }}.</h1>

Will render as follows:    
    <h1>Today.</h1>

Comments may contain newlines.

{{! blah }}

{{!--  blah --}}
