Please update the docs page for EuiHighlight (http://localhost:8030/#/utilities/highlight) to include a switch to turn this functionality on/off - an example of this can be found at

eui/src-docs/src/views/badge/badge.js

Line 77 in fc3d292

<EuiSwitch

(http://localhost:8030/#/display/badge).

In addition, can you try to activate the Props tab for this component? This will require modifying src-docs/src/views/highlight/highlight_example.js to import EuiHighlight can add it to a props object. For reference, you can see how the Badge page's Props tab is setup at

eui/src-docs/src/views/badge/badge_example.js

Line 117 in fc3d292

props: { EuiBadge },
