Product Finder Mega Menu with Filters

A panel containing controls rather than only links. The interaction trap is specific: a control inside a hover-opened panel must not close it, and real inputs need the panel to stay open on click, on drag and while a keyboard user moves between fields. Built with genuine <input> elements, no surrounding form, and a live result count.

Demo: Product Finder Mega Menu with Filters
Source: https://codefronts.com/navigation/css-mega-menus/precision-outdoor-gear-finder/

A panel containing controls rather than only links. The interaction trap is specific: a control inside a hover-opened panel must not close it, and real inputs need the panel to stay open on click, on drag and while a keyboard user moves between fields. Built with genuine <input> elements, no surrounding form, and a live result count.

const root = document.querySelector('.mm-19');
const item = root.querySelector('.mm-19__item');
const panel = root.querySelector('.mm-19__panel');
const trigger = root.querySelector('.mm-19__trigger');
const countEl = root.querySelector('[data-mm-19-count]');
const priceEl = root.querySelector('[data-mm-19-price]');
const slider = root.querySelector('.mm-19__slider');
const boxes = Array.from(root.querySelectorAll('input[type="checkbox"][data-mm-19-filter]'));

const recount = () => {
  const picked = boxes.filter((b) => b.checked).length;
  const ceiling = Number(slider.value);
  const total = Math.max(6, Math.round((420 - picked * 62) * (ceiling / 420)));
  if (countEl) countEl.textContent = String(total);
  if (priceEl) priceEl.textContent = '£' + ceiling;

How this works

Controls change the close policy completely. A links-only panel can close when the pointer leaves, because leaving means the user is done. A panel with a range slider cannot: dragging the thumb routinely takes the pointer outside the panel's box, and a pointerleave close throws the whole interaction away mid-drag. The rule that works is to close on focus leaving the panel, plus a click outside, plus Escape.

Clicking inside must never bubble into a close. If the nav has a document-level click handler that closes any open panel, every checkbox tick closes the panel the checkbox is in. Scope the close to clicks outside the panel and let everything inside behave normally — no stopPropagation(), which breaks other listeners in ways that are hard to trace later.

Use real controls and real grouping. Native <input type="checkbox"> and <input type="range"> come with keyboard operation, correct roles, and platform styling that respects the user's own settings; accent-color tints them to the brand in one line. Wrapping each facet in a <fieldset> with a <legend> means a screen reader announces "Activity, checkbox, trail running" rather than an unattached checkbox.

Announce the result, not the panel. The count is the only thing that changes as filters are applied, so it is the only thing with aria-live. Putting the live region on the panel itself would re-announce the whole filter set on every tick. And note there is no <form> here at all — the panel updates a count and a <button type="button"> takes the user to results, which is also what makes this safe inside a sandboxed iframe with no form submission.

Make it yours

  • Change --mm-19-accent to retint every native control at once through accent-color.
  • Add a facet by copying a <fieldset>; the count script reads all checked inputs generically.
  • Swap the range input for two number inputs if an exact price bracket matters more than a feel.
  • Add a reset control by clearing every input's checked and firing one input event to refresh the count.
  • Retune the panel width with --mm-19-panel-w; the facets reflow with auto-fit.
  • Set the default filter state by adding checked to whichever inputs match your most common search.

Gotchas — read before shipping

  • Closing the panel on pointerleave destroys a range drag the moment the pointer crosses the panel edge, which is the most common bug in filter panels.
  • A document click handler that closes any open panel closes it on every checkbox tick. Scope the close to clicks outside the panel.
  • Wrapping the controls in a <form> inside a sandboxed iframe without form permission means a stray Enter press does nothing visible and looks broken. Use a plain button.
  • aria-live on the whole panel re-announces every label each time a filter changes. Put it on the count alone.
  • Styling checkboxes with appearance: none and a custom box loses the platform focus ring and high-contrast rendering. accent-color gets ninety per cent of the design for none of the cost.

Floor set by :has(), oklch(), color-mix(), text-wrap as this demo is written. The core technique itself goes back further — Chrome 111+.

oklch() and the :has() theme toggle set the floor; accent-color needs Chrome 93, Safari 15.4 and Firefox 92, which lands exactly on the same Safari line and below the others. Where accent-color is unsupported the controls render in the platform default colour and every filter still works; below the oklch() floor the sRGB hex declared first applies.
