Can Vue allow for the inclusion of HTML elements to store data seamlessly?

Question

Can Vue allow for the inclusion of HTML elements to store data seamlessly?

One example involves displaying array elements in an <ul>, with each element starting with <li> and ending with </li>. Here is the attempted code:

clearedtaskslist: function(){
this.template='<ul>'      
for(let i=0;i<this.archive.length;i++)
{
  this.template+= '<li>' + this.archive[i].task '</li>'
}
this.template+='</ul>'
}

Is it possible to implement this functionality in vue?

Edit:

I need to display data from various events, but using v-for only results in the last event data being printed. For instance, I have to show completed tasks and the user who completed them every time someone triggers the related event.

clearedtaskslist: function(){
      
for(let i=0;i<this.archive.length;i++)
{
  this.template += 'Task:  ' + this.archive[i].task 
  this.template +=  ' user: ' + this.archive[i].taskuserID + '----||----'
}

}

This is how I retrieve the data and concatenate strings. However, I need to break the line after each cycle (and I am unsure how to do it).

<div style="margin: 0 auto; margin-top: 25px;" class="w-50">
   <h5 v-if="archive.length>0"><i>Completed tasks</i></h5>
  <div style="margin:0 auto;"> <p>{{template}}</p> </div>
</div>

This is where the data is displayed. The goal is to style the data effectively without relying on cumbersome string concatenation. Is there a way to achieve this in Vue?

After analyzing the scenario, I crafted an illustrative example resembling your situation. However, please keep in mind that adjustments may be necessary to tailor it to fit your specific requirements, given my limited understanding of your application's scope.

<template>
  <div class="hello">
    <div class="buttons">
      <button
        v-for="(user, index) of getUniqueUsers"
        :key="user+index"
        @click="selectedUser=user"
      >User: {{user}}</button>
    </div>
    <ul v-if="selectedUser">
      <li
        v-for="(task, index) of archive.filter((user) => user.taskuserID==selectedUser)"
        :key="task+index"
      >
        <p>User: {{task.taskuserID}}</p>
        <p>Task: {{task.task}}</p>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  name: "HelloWorld",
  data() {
    return {
      selectedUser: null,
      archive: [
        {
          taskuserID: "1",
          task: "task1"
        },
        {
          taskuserID: "2",
          task: "task3"
        },
        {
          taskuserID: "1",
          task: "task3"
        },
        {
          taskuserID: "4",
          task: "task4"
        },
        {
          taskuserID: "5",
          task: "task1"
        }
      ]
    };
  },
  computed: {
    getUniqueUsers() {
      const uniqueUsers = [
        ...new Set(this.archive.map(user => user.taskuserID))
      ];
      return uniqueUsers;
    }
  }
};
</script>

<style scoped>
.buttons {
  display: flex;
  justify-content: space-around;
}
</style>

The example incorporates a fictitious archive data property, which is an array of objects storing taskuserID and task details.
A computed property was utilized to extract unique taskuserID values from the archive array.
By iterating through the sorted array of unique users using v-for, individual buttons are generated for each user selection.
Upon clicking a button, the subsequent loop displays all tasks associated with the chosen taskuserID by filtering the archive array based on the selected user value.
