The Knight WordPress theme is mobile and responsive.
Theme has been integrated with Slicknav Menu plugin (let me highlight this – the menu integration is multi-level JQuery touch responsive menu).
The site is designed so that left sidebar with its widgets gets removed on mobile browsers but the footer 3 widgets remain and stack vertically.
To activate the bile menu you need to install plug-in “SlickNav Mobile Menu”.
WP admin > Plugins > Add New > (search) SlickNav Mobile Menu
or install it by uploading the zipped version.
Configure the Slicknav Mobile Menu
WP Admin Panel > Settings > SlickNav Menu
Two essential settings you need to enter are:
“Add Menu Replace” field.
Type #primary-menu in the form field.
“Pixel Width to Switch to SlickNav” enter 1024 in that field and press UPDATE at the bottom of the page to save the changes.
