The generated catalog pages rendered the "Source" accordion title as a
JSX expression, `<Accordion title={`name.html`}>`. Mintlify's search
indexer stringifies expression attribute nodes rather than evaluating
them, so every one of the 399 catalog pages surfaced its Source section
in search results as "[object Object]" (visible on the Scroll Feed page,
among others).
The template literal carried no escaping benefit: every title is a
single-segment `name.html` path, and a double-quoted JSX string handles
it directly. Introduce `mdxStringAttribute`, which emits a plain
`name="value"` attribute and escapes `& " < { }` as HTML character
references (MDX decodes references inside quoted attribute values, and
unlike JSON.stringify it does not rely on backslash escapes, which JSX
strings do not honour). Use it for both the Source accordion title and
the preview iframe title, and regenerate the catalog pages.
Regenerated with `npx tsx scripts/generate-catalog-pages.ts`; the only
change across the 399 pages is the one Accordion title line each.

## Install
|
||
|
||
<InstallCommand command="npx hyperframes add mk-background" item="mk-background" />
|
||
|
||
That writes one file: `compositions/mk-background.html`.
|
||
|
||
<iframe
|
||
className="w-full aspect-video rounded-xl border-0 bg-zinc-100 dark:bg-zinc-800"

||
title="mk-background preview"

## Add it to your video
|
||
|
||
It runs for 10 seconds at 1920×1080. Paste this into your composition:
|
||
|
||
```html index.html
|
||
<div
|
||
data-composition-id="mk-background"
|
||
data-composition-src="compositions/mk-background.html"
|
||
data-start="0"
|
||
data-duration="10"
|
||
data-track-index="1"
|
||
data-width="1920"
|
||
data-height="1080"
|
||
></div>
|
||
```
|
||
|
||
Move it in time with `data-start`. Put it on a different timeline row with
|
||
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.
