- Pick element Child to be
position: sticky. Ensure it has a one of the following set: top,bottom,left,right
- Ensure it has a parent that has
position: relative
- Ensure that all elements between the parent and child have
overflow: visible
- Next.js sets
overflow:disabled on the entire document by default
- Many MUI elements will have
overflow: hidden set, check all parents for this.
- Easiest to diagnose this by selecting child in Inspect Element, filter styles for "overflow" and click up repeatedly to traverse up the DOM.
