How to add comments into a mustache template?

Question

In my Mustache template, I would like to comment a couple of lines, but I am unable to do it. I am still getting the comments displayed in HTML. What is the correct way to add comments? Anyone can help me to sort this out please?

here is my code:

<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>

Answer 1

Mustache documentation suggests to use following for comments:

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.

I assume that in your case you had to use

{{! blah }}

Instead of

{{!--  blah --}}

Answer 2

You are trying to comment on mustache template that also has html in it, so you actually have to add mustache comment where the mustache code is and html comment where the html code is.
