hey Robert Drew Jeffrey,

yeah it's possible and for this you have to change following files:

1) src\menu\adapt-contrib-boxMenu\templates\boxmenu-item.hbs

here, remove the below code:

<span class="menu-item-duration">Duration: {{{duration}}}</span>

<div class="menu-item-progress">
    <div class="menu-item-progress-indicator">
        <div class="menu-item-progress-indicator-bar" style="height:{{completedChildrenAsPercentage}}%;"></div>
    </div>
</div>

Note: this will actually removes the menu-progress-bar and duration from course menu and below two steps are optional.

2) src\menu\adapt-contrib-boxMenu\less\boxmenu.less

here, you should remove all the irrelevant classes which was previously removed in hbs.

 e.g. .menu-item-duration, .menu-item-progress etc

3) src\course\en\contentObjects.json

here, you should remove the below json entries.

"linkText":"View",
"duration":"2 mins"

and that's all.

Thanks,

Himanshu
