**Expected behavior:**

I want to highlight the pathMatch 'menu' when user redirect to the child page
**Steps to reproduce:**

Here is the menu setting snap:
{
title: 'Order Manage',
icon: 'nb-grid-b',
children: [
{
title: 'Order List',
link: '/pages/order/order-list',
},
{
title: 'Order Detail',
link: '/pages/order/order-detail',
pathMatch: 'order-list',
hidden: true
}
],
},

refer to the above code, the menu 'order-detail' is hidden as expected, but when I redirect to the path 'http://localhost:4200/#/pages/order/order-detail', the menu 'order-list' doesn't be highlighted as expected, please advise. Thanks in advance
