Hello folks,

I am looking for a code to stop "Especializaciones" going onto the next line. There is definitely space for them all to fit and still be centered  🙄

 Could you help me please? 🙏🙏

ps. there's not password in the web

Try adding to Design > Custom CSS

/* Nav one line */
.header-title-nav-wrapper {
    flex: 1 0 90%;
}
.header-layout-nav-center .header-nav {
    width: 100% !important;
    flex: 1 1 100%;
}
