I included three times the 'WooCommerce Layered Nav' widgets.
The problem I had with this, I wanted this widgets not to be 'individual' in my HTML structure, but it needed to be one 'section'. So I managed to this this by changing the HTML values of this widgets, see my image.
But now the problem. Then I only had ONE SHOPPING CATEGORY, showing always these three widgets so it was easy to put HTML before the first widget and to put HTML after the last widgets.
But now I have a new category and planning to do lot's more, where for example only one WooCommerce Layered Nav widgets is showing:
Now my functions.php does not work anymore for this and my HTML structure I wanted is gone...
is wrapping the three 'WooCommerce Layered Nav' widgets, in one HTML
with the title 'Keuzehulp' > changing the before and after value of the first and last 'WooCommerce Layered Nav' widget, that is what you can see on the previous provided image.
At that moment, I only had one shopping category, and I always knew these three 'WooCommerce Layered Nav' widgets would be on the page, so the HTML would be the way I wanted.
But now I had created an extra category, that is only showing ONE 'Woocommerce Layered Nav' widget, and because of that my HTML that I have added before the nav-3 woocommerce layered nav widget is not included anymore, since this nav-3 widgets is not showing on that category page...
