When pressing # the popup is not triggered.

The idea to use make hashTag Input with auto complete. HashTag string should be bold.

The problem is with your input container, it is not a native input container. react-autocomlete-input uses library, which natively evaluates caret position by calling either selectionStart and selectionEnd for modern browsers or document.selection.createRange() for legacy like IE < 11.

Div doesn't support those APIs, therefore you see this error. Try input or textarea instead
