Sequence of html rendered on page :
1. Textbox, empty calendar
2. Calendar renders events
3. Type in the textbox to get auto-complete dropdown.
Can I show the autocomplete dropdown on top of calendar event divs? Thank you,

Fix :
Z-idex worked together with position absolute : z-index: 10 ;position: absolute; top: 200px;
Look into the CSS property z-index. You can set the z-index of the dropdown to be larger than the other elements.
Careful on how you implement this. A common approach is to use intervals of 10 for the z-index, and something like 9999 as the “roof” that you know will never be exceeded. This ensures that in the future you can continue to add elements “between” existing ones.
