Estimados, estoy editando la plantilla cosmos de bootstrap 3, para editar el menu tengo que editar primarynavmenu.tpl ?
ojs/plugins/themes/bootstrap3/templates/frontend/components ?
ayuda porfi! 
Hi @priscila,
Yes, the navigation menu is implemented in templates/frontend/components/primaryNavMenu.tpl for that theme. You could either edit the file, or create a child theme – see OJS 3: Need help with theme customization
for some details.
