To create an input field that accepts tags First, we need to :

• Define a TagInput component and use the useState() hook to initialize an array from tags.
• Use Array.prototype.map() on the collected nodes to render the list of tags.
• Define the addTagData method, which will be executed when pressing the Enter key.
• The addTagData method calls setTagData to add the new tag using the spread (...) operator to prepend the existing tags and add the new tag at the end of the tagDataarray.
• Define the removeTagData method, which will be executed by clicking the delete icon in the tag.
• Use Array.prototype.filter() in the removeTagData method to remove the tag using its index to filter it out from the tagData array.

CSS file can be styled to your own preference

.tag-input {
  display: flex;
  flex-wrap: wrap;
  min-height: 48px;
  padding: 0 8px;
  border: 1px solid #d6d8da;
  border-radius: 6px;
}

.tag-input input {
  flex: 1;
  border: none;
  height: 46px;
  font-size: 14px;
  padding: 4px 0 0;
}

.tag-input input:focus {
  outline: transparent;
}

.tags {
  display: flex;
  flex-wrap: wrap;
  padding: 0;
  margin: 8px 0 0;
}

.tag {
  width: auto;
  height: 32px;
  display: flex;
  align-items: center;
  justify-content: center;
  color: #fff;
  padding: 0 8px;
  font-size: 14px;
  list-style: none;
  border-radius: 6px;
  margin: 0 8px 8px 0;
  background: #0052cc;
}

.tag-title {
  margin-top: 3px;
}

.tag-close-icon {
  display: block;
  width: 16px;
  height: 16px;
  line-height: 16px;
  text-align: center;
  font-size: 14px;
  margin-left: 8px;
  color: #0052cc;
  border-radius: 50%;
  background: #fff;
  cursor: pointer;
}

let's Create the TagInput Component

const TagInput = ({ tags }) => {
  const [tagData, setTagData] = React.useState(tags);
  const removeTagData = indexToRemove => {
    setTagData([...tagData.filter((_, index) => index !== indexToRemove)]);
  };
  const addTagData = event => {
    if (event.target.value !== '') {
      setTagData([...tagData, event.target.value]);
      event.target.value = '';
    }
  };
  return (
    <div className="tag-input">
      <ul className="tags">
        {tagData.map((tag, index) => (
          <li key={index} className="tag">
            <span className="tag-title">{tag}</span>
            <span
              className="tag-close-icon"
              onClick={() => removeTagData(index)}
            >
              x
            </span>
          </li>
        ))}
      </ul>
      <input
        type="text"
        onKeyUp={event => (event.key === 'Enter' ? addTagData(event) : null)}
        placeholder="Press enter to add a tag"
      />
    </div>
  );
};
