I have this menu in nodejs (jade / pug)
extends ../templates/default
block content
nav#colorNav
ul
li.green
a.icon-home(href='#')
ul
li
a(href='#') Generar
li
a(href='#') Cierre
li
a(href='#') Conteo
li.red
a.icon-cogs(href='#')
ul
li
a(href='#')
li
a(href='#')
li
a(href='#')
li
a(href='#')
li.blue
a.icon-twitter(href='#')
ul
li
a(href='#')
li
a(href='#')
li.yellow
a.icon-beaker(href='#')
ul
li
a(href='#')
li
a(href='#')
li
a(href='#')
li
a(href='#')
li.purple
a.icon-envelope(href='#')
ul
li
a(href='#')
and it looks like this
What I want to do is that when I click on the generate item, for example, I would create a h3 = 'Generate' but without leaving the menu, which is on the same page.
