Let's create a tag input

The structure of the tag input

The important part of the code

• The x-data attribute is used to define the data of the component

• The x-for attribute is used to loop through the tags array

• The :key attribute is used to uniquely identify each item in the loop

• The x-text attribute is used to display the value of the tag variable

• The @click attribute is used to add a new tag to the tags array when the user clicks the close button

Note: The classes are remove for clarity.

<div

  x-data="{
        tags: [],
        addTag(tag) {
            if (tag.trim() !== '') {
                this.tags.push(tag.trim());
            }
        },
        removeTag(index) {
            this.tags.splice(index, 1);
        }
    }">
  <!-- Tag Input -->
  <div
    class="w-full"
    x-data="{ newTag: '', tags: [] }">
    <!-- Input Field -->
    <input
      x-model="newTag"
      @keydown.enter.prevent="
            if (newTag.trim() !== '') {
                tags.push(newTag.trim());
                newTag = '';
            }
        "

      type="text"
      placeholder="..."
    />
    <!-- Tags will be added here -->
    <div>
      <template
        x-for="(tag, index) in tags"
        :key="index">
        <div
          >
          <span x-text="tag"></span>
          <button
            @click="tags.splice(index, 1)"
            class="ml-2">
            <!--- Close Icon goes here -->
          </button>
        </div>
      </template>
    </div>
  </div>
