[EuiComboBox] Break long strings properly when `rowHeight="auto"` by acstll · Pull Request #9063 · elastic/eui

acstll · 2025-09-29T10:10:16Z

Summary

This is a follow-up to #8934

It introduces a tiny update to the styles of the Combobox options, ensuring that long strings without spaces wrap. Without awkwardly breaking regular sentences as applying word-space: break-word would.

That (having long strings without spaces wrap) was made possible in #8934 by introducing variable heights in the options list (rowHeight="auto"). But a bit of code was required from the consumer side, namely using the renderOption prop.

Before (with initial enhancement #8934)

renderOption: (option, searchValue) => {
  return (
    <EuiHighlight search={searchValue} style={{ wordBreak: 'break-word' }}>
      {option.label}
    </EuiHighlight>
  );
},

After (this PR)

// 🧹

Why are we making this change?

This PR aims to completely fulfill the request made in #7712 without introducing any breaking changes (pun intended).

Screenshots

Only rowHeight="auto" needed

packages/eui/src/components/combo_box/combo_box_options_list/combo_box_options_list.styles.ts

        text-align: start;
+        /* Allow long strings without spaces to break,
+           while keeping regular sentences wrapping as expected */
+        overflow-wrap: anywhere;


Good call! And it's widely enough supported 🎉

🟢 Code changes LGTM. I tested the functionality tested in Storybook and EUI docs against prod and it works as expected 👍
