Replace your theme header

Everything your theme’s header never could do.

Flow Nav is a powerful, zero-dependency WordPress plugin that replaces your theme’s native header with a fully featured sticky bar — no page builder required, no shortcodes, no fuss. Built entirely from PHP, CSS, and vanilla JavaScript, it integrates directly with your existing WordPress menus and works cleanly across virtually any theme right out of the box.

Every aspect of the header is configurable from a single settings page: header height, scroll threshold, transition speed, background colours with opacity control, logo scaling, content width and padding, and a full-screen mobile overlay menu.

Intelligent scroll behaviours

One threshold.
Three smart behaviours.

All three scroll behaviours — hide on scroll, colour transition, and header shrink — fire at a single configurable threshold you set once in pixels or viewport height. Flow Nav keeps your header completely unobtrusive until it’s actually needed, then brings it back instantly the moment your visitors want it.

Set your threshold once.

Hide on scroll down

The header slides smoothly out of view as visitors scroll down — reappearing immediately the instant they scroll up.

Colour change past the hero

Background colour, text colour, and logo swap automatically once the visitor scrolls past your hero section — keeping contrast perfect on every section.

Proportional shrink

The header and logo scale down proportionally as visitors scroll past the threshold — giving more screen space to your content without disappearing entirely.

Set in px or vh

Define your scroll threshold in pixels for precise control, or in viewport height units for a responsive value that adapts to every screen size.

All features

Everything you need in a modern WordPress header

Flow Nav is packed with features that give you complete design and behaviour control — all from one clean settings page.

Hide on scroll down

The header slides out of view as visitors scroll down and reappears immediately when they scroll up — keeping the screen uncluttered.

Hero colour swap

Background, text, and logo colours switch automatically once visitors scroll past your hero — perfect contrast on every section, always.

Proportional shrink

Header and logo scale down proportionally past the threshold — giving more screen real estate to your content without hiding the nav entirely.

Mega menu with rich cards

Tag any menu item with ssh-megato display a full-width panel with featured image cards for linked pages.

Full-screen mobile overlay

The hamburger expands to a centred full-screen overlay with a smooth fade and animated ×, with its own background and text colour settings.

WooCommerce ready

Cart icon with live item count via cart fragments and My Account link appear automatically when WooCommerce is active — no setup required.

CTA button built in

A fully customisable call-to-action button lives in the header — set the label, URL, background colour, text colour, and border radius from the settings page.

Total design control

Every colour, size, padding, opacity, logo scale, and transition speed is configurable from a single admin settings page — changes reflected immediately on save.

Zero dependencies

Built entirely from PHP, CSS, and vanilla JavaScript — no jQuery, no external libraries, no page builder. Lightweight, fast, and conflict-free.

Mega menu

Beautiful dropdown panels — with one CSS class.

Tag any WordPress menu item with ssh-megaand Flow Nav automatically generates a full-width mega menu panel — displaying linked pages with their featured image, title, and description in a polished card layout.

No custom templates, no shortcodes, no third-party mega menu plugin. Flow Nav reads your existing WordPress menu structure and builds the panel automatically.
