UI kit toggle hamburger menu not showing


I have a line of code from UIkit 3.0 that displays a hamburger menu

<a className="uk-navbar-toggle" uk-navbar-toggle-icon href=""></a>

However the hamburger menu icon does not show.

I am using React.

How do i pass the attribute uk-navbar-toggle-icon so that it works.

I get this warning

If you want to write it to the DOM, pass a string instead: uk-navbar-toggle-icon=“true” or uk-navbar-toggle-icon={value.toString()}.

Nothing happens when I type in the =“true” or pass the attribute as a string.

Please help!
