Faq89: Filterable Glossary

A jargon glossary whose letter filter is derived from the terms themselves, narrowing a two-column hairline definition list with an empty state and a suggest-a-term action.

Installation

Radix flavor

npx shadcn add "https://ui.beste.co/r/faq89"

Base UI flavor

npx shadcn add "https://ui.beste.co/r-base/faq89"

This installs the block to components/beste/block/faq89.tsx plus the badge23 and button21 components it uses for the eyebrow and the closing action.

Quick start

The installed file exports faq89Demo alongside the block: the exact props behind the preview above. Spread it to get a working glossary in one line.

import { Faq89, faq89Demo } from "@/components/beste/block/faq89";

export default function GlossaryPage() {
  return <Faq89 {...faq89Demo} />;
}

Then replace the demo with your own props. Written out, a trimmed setup looks like this:

import { Faq89 } from "@/components/beste/block/faq89";

export default function GlossaryPage() {
  return (
    <Faq89
      badge={{ label: "Plain English" }}
      heading="The words we use, and what we actually mean by them"
      description="Clinical software collects vocabulary. Here is ours."
      allLabel="All"
      terms={[
        {
          term: "Backfill",
          definition: "A cancelled slot offered to the waiting list automatically.",
        },
        {
          term: "Seat",
          definition: "One person with a login, prorated in both directions mid-month.",
        },
      ]}
      emptyLabel="Nothing filed under that letter."
      closing="Missing a word you keep having to explain to us?"
      button={{ label: "Suggest a term", href: "/contact" }}
    />
  );
}

Props

type ActionLink = {
  label: string;
  href: string;
};

type Term = {
  term: string;
  definition: string;
};

Behavior notes

• The letter buttons are derived from the first character of each term, uppercased, deduplicated and sorted. Adding a term starting with a new letter adds its button automatically.
• Only letters that have terms behind them are shown, so there is no row of dead buttons for the letters you have not used yet.
• Terms are never sorted by the block. The letters are sorted, but the list itself renders in array order, so pass them alphabetically if that is what you want to read.
• The active filter is one piece of state holding either a letter or null, with null meaning unfiltered. The all-pill is the same control rather than a special case.
• Letter buttons are square (size-9) while the all-pill sizes to its label, which keeps the row reading as one control group without forcing "All" into a square.
• The list is a real dl with dt and dd per entry, split 1fr to 2.4fr from md, so definitions get most of the width.
• Rows carry border-t with no closing rule, so the list flows into the closing row, which brings its own hairline.
• Filter buttons carry aria-pressed and explicit cursor-pointer, since Tailwind v4 buttons default to cursor: default.
