Autoheight

Dropdown compositions that hug content: search, titles, icons, checks, dividers, and sticky footers.

Drill-in

Open Filter and choose Model or Browser. The pane slides over and the menu height eases to the new list in 200ms, then back when you return.

Maximum height

Height is capped at 500px or the space available. Past the cap the list scrolls with a fade while the search and footer stay pinned.

Best practices

When to use

  • Use when a bounded surface switches between known content states (drill-in panes, filtered lists) and the height change should feel continuous.
  • Avoid it for long, frequently changing lists where scrolling is clearer and less distracting.

Behavior

  • Dropdown height counts the header, search, list and footer, and caps at 500px or the space available, after which the list scrolls with a fade.
  • Pane changes ease over 200ms; respect reduced motion and never clip focus rings or interactive content.
