My website have many posts, ~9 main categories and "unlimited" subcategories.
I'd like to force in WordPress panel that you can't choose more than 1 top level category but you can choose unlimited subcategories of this main one.
One plugin changed checkboxes into radiobuttons and it works great but only for one level and I need more depth.
Is there any way to do that? Thanks in advance.

Reset to default 0Late answer but I figured I'd throw in my idea since I had a similar problem recently.
Basically I did this by injecting a script into the editor views. My function looked something like this:
(function() {
var o=function() {
//add a click handler to category checkboxes
jQuery("#categorychecklist input").click(function() {
//get top-level category (in case child is checked)
var tlc = jQuery("#category-all>ul>li").has(this);
//if top-level category is not checked, check it
jQuery(">label>input",tlc).prop("checked", true);
//uncheck all boxes from other top-level categories
jQuery("#category-all>ul>li").not(tlc).find("input:checked").prop("checked", false);
});}
//run this function onload
var n=window.onload;"function"!=typeof window.onload?window.onload=o:window.onload=function(){n&&n(),o()};
})();
I hope this helps somebody. To add a script just use something like this: How to enqueue scripts on custom post add/edit pages?
