SharePoint Blog - Restrict to a Single Category

Question

Hi - we're using SharePoint 2013 Blogs to implement a news site. However, we'd like the users to be restricted to only selecting a single category of post.
Can anyone advise on the easiest method to achieve this?
Thanks for your help.

Hi Simon,
Category field can't seem to be modified/configured to only select a single value OOTB from SharePoint 2013 Blog site Posts list, however we can use JQuery to disable the "Add" button when we selected one category value for new
item from NewPost.aspx and EditPost.aspx for the Posts list.
Please go to Posts list then click "Default New From" for editing the NewPost.aspx page then add a"Content Editor" webpart (or "Script Editor" webpart), then paste the following code without any modification, and then save
the webpart and page, then it will work (and repeat for "Default Edit Form" for EditPost.aspx).
If there is any unclear, please feel free to post.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script><script type="text/javascript">
$(document).ready(function(){
$("#PostCategory_38bea83b-350a-1a6e-f34a-93a6af31338b_SelectCandidate").change(function(){
$selected = $("#PostCategory_38bea83b-350a-1a6e-f34a-93a6af31338b_SelectResult");
if ($selected.find('option').length>0)
$button = $("#PostCategory_38bea83b-350a-1a6e-f34a-93a6af31338b_AddButton");
$button.attr("disabled", "disabled");
else
$button = $("#PostCategory_38bea83b-350a-1a6e-f34a-93a6af31338b_AddButton");
$button.removeAttr("disabled");
</script>
