Hi! I cannot access the snippet so im not sure if my snippet will help you.

I created a simple autocomplete input and added a button that will close the autocomplete popper. To make the popper stay after clicking outside I added keepOpen prop to the MDBAutocomplete component. You can find the snippet here:

If your issue is resolved, please let me know in a comment, and if it's still there, can you check if there is a publish button in the top right corner (next to save button)? Click on it, otherwise please share some code here. Best Regards!
