- Fix: resolve search dropdown clickability by increasing z-index. The DocSearch button and dropdown were not clickable due to z-index conflict with sticky sidebar elements. Added position: relative and z-index: 501 to .docsearch .DocSearch-Button, and z-index: 500 to .docsearch wrapper to ensure proper stacking context.
