Show/Hide Based on Button State

fixed the issue. Will look into that further I think I found your problem. In your handleClick method, you change the state to false to hide your list. When one presses the button again to show the list, all they are doing is setting the state to false again. Flip the state like this:
code :
handleClick() {
  this.setState({ linksHidden: !this.state.linksHidden });
handleClick() {
  this.setState(state => ({ ...state, linksHidden: !state.linksHidden }));

should help you out So, the way you are doing this isn't really good for a number of reasons. It's very inflexible and requires that you change both your HTML and Javascript whenever your staff assignments change.
Here's how I approached this. I have an array-like object with staff (like you might retrieve from a database), and the staff have contact info and a list of states they are associated with. When the user chooses a state, we look at each "rep" and see if they service that state and add them to the displayed list if so. If you need to change the assignments around, you just need to edit that one object.
code :
var reps = {
  Justin: {
    states: ["AL", "AR"],
    contact: { name: "Justin", phone: "555-123-4567" }
  Jess: {
    states: ["AR", "MS", "LA"],
    contact: { name: "Jess", phone: "555-234-5678" }
  Rob: {
    states: ["NC", "SC"],
    contact: { name: "Rob", phone: "555-345-6789" }

$("#state").on("change", function() {  

  var selectedState = $(this).val();
  if (!selectedState) {
  var noReps = true;
  Object.keys(reps).forEach(function(repKey) {
    var rep = reps[repKey];
    if (rep.states.includes(selectedState)) {
      noReps = false;
        "<li>" + rep.contact.name + " - " + rep.contact.phone + "</li>"
  if (noReps) {
  } else {
