When highlightFirst is false, it should look like this:

Instead, it looks like this:

to fix it, open mdb-angular-ui-kit-select.js and find the open() function. You should see an if statement:

if (overlayRef && !overlayRef.hasAttached()) { overlayRef.attach(this._portal); this._listenToOutSideClick(overlayRef, this.input).subscribe(() => this.close()); this._highlightFirstOption(); }

change

this._highlightFirstOption();

with:

if(this._highlightFirst) { this._highlightFirstOption(); }
