Bootstrap dropdown is not toggling when using it with data target.

If I remove data-target from button then it works but I my website dropdown open on second click, so I searched for solution that is use of data-target but after using it its not toggling.

use dropdownnotifyButton instead of #dropdownnotifyButton

Elements are failing to match with the data-target specified. Remove # from data-target value.

Change

data-target="#dropdownnotifyButton"

To

data-target="dropdownnotifyButton"
