Hi! Is there a Readme file with the instructions?

For now I included the functions in functions.php, I put the php file in a assets folder.

With bs4navwalker I had to use only this command in functions.php : require_once('assets/bs4navwalker.php');
Later I put the dynamic menu in header.php.

How can I do to include your uikitwalker?
Thanks
Carlo

Hi @tasz

Thank you very much for your answer. Now it's ok for the desktop but I don't see anything when clicking on the mobile-menu-button, simply I see the button disappear, using the off-canvas menu. I do some changes like my off-canvas menu but nothing changed.

Have I to change the 'your_themename' with the name of my theme?

This is how I have the off-canvas menu

/**

I have add the following markup
<div class="uk-navbar-dropdown uk-navbar-dropdown-width-2"> <div class="uk-navbar-dropdown-grid uk-child-width-1-2" uk-grid>

in line 17 and 207 , the 2 columns are shown correctly, but the menu items remain in one column!

thank you
