How do I improve a concept nav dropdown purpose from on hover to on click?

Like the title claims, I am custom coding a web page working with a blank []( concept. On the key navigation the default function for a nav dropdown is on hover, how would I improve it to on click on? Its my perception that on simply click navigations are improved than on hover for folks with disabilities correct? I have used []( for about 3 decades now and I appreciate it, but I constantly just custom coded a navigation on the header.php, but that makes modifying the navigation on the shopper facet just about impossible without having enhancing the php file. Im just making an attempt to take gain of the wordpress menus attribute.
