Creating dynamic templates and embellishments in VUE

My VUE components, including Field and Form, are able to dynamically render a form based on the provided data.

<template> 
  <form @submit="$emit('submit', $event)" >
    <template v-for="(item, index) in form.elements">     
      <Field
        v-model="value[index]" 
        :label="item.options.label"  
        :type="item.type"      
      />
    </template>
  </form>
</template>

I am able to render a form by passing structured data.

<Form :form="formStructure" v-model="state" @submit="save()" />

By using the formStructure object, the form elements are displayed in the specified order.

My goal is to enhance the appearance of the Form component by adding a custom template for decoration.

<Form :form="formStructure" v-model="state" @submit="save()" >
  <template >
     <div class="row">
        <div class="col-4"><i class="icon-user"></i> <!-- Field component will be rendered here by Form component --> </div>
        <div class="col-8"><i class="icon-mail"></i> <!-- Field component will be rendered here by Form component  -->     </div>
     </div>
     <h2>A Custom Header</h2>
     <div class="row">
       <!-- another row with other elements-->
     </div>
  </template>
</Form>

The structure of the form data looks something like this:

{
   "form":{
      "method":"post",
      "id":"formF75a1543a"
   },
   "elements":{
      "username":{
         "type":"inputtext",
         "options":{
            "label":"Pick a username"
         }
      },
      "email":{
         "type":"inputtext",
         "options":{
            "label":"Your e-mail"
         }
      }
   }
}

What steps should I take to achieve this customization?

Answer №1

Through extensive research, I finally discovered the solution. It turns out that simply using slots was not sufficient to address the issue at hand. Utilizing teleportation proved to be the key.

<!-- The Form Component -->
<template> 
  <form @submit="$emit('submit', $event)" >
   <slot name="default" ></slot>  
    <template v-for="(item, index) in form.elements">     
     <teleport :to="'#'+index" :disabled="!fieldTargetExists(index)">
      <Field
        v-model="value[index]" 
        :label="item.options.label"  
        :type="item.type"      
      />
      </teleport>
    </template>
  </form>
</template>
<!-- Using component with a template -->
<Form :form="formStructure" v-model="state" @submit="save()" >
  <template >
     <div class="row">
        <div class="col-4"><i class="icon-user"></i> <span id="username"></span> </div>
        <div class="col-8"><i class="icon-mail"></i> <span id="email"></span> </div>
     </div>
     <h2>A Custom Header</h2>
     <div class="row">
       <div id="submit"></div>
     </div>
  </template>
</Form>
