Tailwind Collapsible Breadcrumb with Ellipsis Dropdown

A file-explorer header whose breadcrumb collapses to Home › ··· › Documents; the ellipsis opens the hidden ancestors as a dropdown that scales out from the button. The port anchors the menu to the ellipsis itself (not a magic top: 88px), adds the click-outside scrim the original's gotchas asked for, and uses real <nav><ol> breadcrumb semantics. Zero JavaScript.

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • The dropdown's position:absolute; top:88px on the app bar became absolute top-full inside the ellipsis <li> — it follows the button whatever the header height.
  • Separator <span>s became before:content-['›'], so assistive tech reads only the path, inside a real <nav aria-label="Breadcrumb"><ol> with aria-current="page".
  • UI upgrade from the CSS original: a transparent scrim label closes the dropdown on outside taps (the original's listed gotcha), the ellipsis stays highlighted while open, and the hidden ancestors are indented to show depth.
  • UI upgrade: file-type badges replace emoji, header buttons grew from 32px to 40px with labels, the storage footer gained a usage bar, and muted copy rose from zinc-500 (4.6:1) to 5.9:1.

How this works

Anchored, not offset. The original positioned the dropdown at top: 88px on the app bar, which broke whenever the bar's height changed. Here the dropdown lives inside the ellipsis <li class="relative">:

<div class="absolute top-full left-0 mt-2 origin-top-left
  invisible scale-95 -translate-y-2 opacity-0
  group-has-checked:visible group-has-checked:scale-100 …">

Close on outside tap. A transparent full-screen <label for> under the dropdown unchecks the toggle — the fix the CSS version listed as a gotcha.

Separators are before: pseudo-elements on each <li> after the first, so screen readers read only the path.

Make it yours

  • Right-aligned: right-0 origin-top-right on the dropdown.
  • Show two levels: move one ancestor out of the dropdown into the visible <ol>.
  • Text-link ellipsis: drop the border/background on the label.
  • Deeper paths: add more links to the dropdown — it grows to fit.

Gotchas — read before shipping

  • The breadcrumb row must not be overflow-hidden, or the anchored dropdown is clipped.
  • The scrim must sit below the dropdown (z-10 vs z-20) or it swallows the menu clicks.
  • Hidden ancestors are still in the DOM; keep the dropdown invisible so they're not tab stops while closed.
