Hi,
You will need to customize the LESS file to achieve that: root/templates/ja_intranet/less/variables.less
In this file, you look for the declaration for Media queries breakpoints & Grid system:
// Point at which the navbar stops collapsing
@grid-float-breakpoint: @screen-lg-min;
You then can change the variable: @screen-lg-min to another variable which are declared above it, you can change it to:
@grid-float-breakpoint: @screen-hd-min;
Once done, you go to admin panel > Extensions > Templates > open JA Intranet template style > General tab and check the status of Development Mode, if it's ON, just refresh your page on frontend to see the change. In case, it's turned OFF, you need to click LESS to CSS button to compile less to css (REMEMBER to backup all current CSS files first).
Regards
