I have placed List webpart to filter some value then pass to other Webpart to display filtered Content.
The following code will hide the List webpart then users will not see those Hidden Value.
you just find that webpart ID and add in the following code.
Add this to Script Editor Webpart. Publish the page then the web part will be hidden.
Work Around Code:
<script type="text/javascript">
document.getElementById('MSOZoneCell_WebPartWPQ6').style.display='none';
</script>
