Dropdown menu in React not showing

Question

I'm trying to create a simple dropdown menu in a card element but am having issues getting the menu to actually show up. I inspected it on Chrome and it says the menu is there but I can't get it to show up on the screen.

constructor(props) {
    super(props);
    this.state = {
        loading: true,
        open: false
    };
}

    toggleDropDown = () => {
    this.setState({ open: !this.state.open });
};

<div className="content">
     <div
         onClick={event => {
             event.stopPropagation();
         }}
         onFocus={() => {
             this.toggleDropDown();
         }}
         onBlur={() => {
             this.toggleDropDown();
         }}
         tabIndex="0"
         className="ui right floated dropdown" >
         <i className="ellipsis vertical icon" />
              {this.state.open ? (
                    <div className="menu">
                         <div className="item">
                              <i className="edit icon" /> Edit Post
                         </div>
                         <div className="item">
                              <i className="delete icon" />Remove Post
                         </div>
                         <div className="item">
                              <i className="hide icon" /> Hide Post
                         </div>
                    </div>
              ) : null}
        </div>
        <div className="header">{schedule.title}</div>
        <div className="description">
              <p>{schedule.description}</p>
        </div>
        <div className="meta">
             <span className="right floated time">
                   {moment(schedule.date).fromNow()}
             </span>
       </div>
 </div>

This is a screenshot of the card I am producing (div with classname content is all that shows up in the picture). Reactjs dropdown menu

The issue is that .menu, although it is appearing in the inspector, is set to display: none.

Here's me disabling the property.

And here's the menu displaying as expected:
