title: Lists are not currently supported in HTML input in rest framework
body: <p>I wanted to design an api for creating a rent information along with gallery(multiple image upload).My models look this </p>
  
  <pre><code>class Rental(models.Model):
      ownerName = models.CharField(_("Owner's Name"),max_length=255, blank=True,null=True,
          help_text=_("Owner's Full Name"))
      renter = models.ForeignKey(User,null=True,blank=True)
      email = models.CharField(max_length=120,blank=True,null=True)
      phoneNumber = models.PositiveIntegerField(blank=False,null=True,
          help_text=_("Phone number of contact person"))
  
  class Gallery(models.Model):
      rental = models.ForeignKey('Rental', null=True, on_delete=models.CASCADE,verbose_name=_('Rental'), related_name="gallery")
      image = models.ImageField(blank=True,upload_to='upload/',null=True)
  </code></pre>
  
  <p><strong>serializers.py</strong></p>
  
  <pre><code>class GalleryListSerializer(ModelSerializer):
      class Meta:
          model = Gallery
  
  class RentalCreateUpdateSerializer(ModelSerializer):
      gallery = GalleryListSerializer(many=True)
      class Meta:
          model = Rental
          exclude = ('id','slug','is_published','created_on','modified_on',)
  </code></pre>
  
  <p><strong>views.py</strong></p>
  
  <pre><code>class RentalCreateAPIView(CreateAPIView):
      queryset = Rental.objects.all()
      serializer_class = RentalCreateUpdateSerializer
      # permission_classes = [IsAuthenticated]
  
      def perform_create(self, serializer):
          serializer.save(user=self.request.user)
  
      def create(self,validated_data):
          ownerName=validated_data.get('ownerName',None)
          renter = validated_data.get('renter', None)
          email=validated_data.get('email',None)
          phoneNumber=validated_data.get('phoneNumber',None)
          image=validated_data.pop('image')
          return Rental.objects.create(ownerName=ownerName,renter=renter,phoneNumber=phoneNumber,email=email,image=image)
  </code></pre>
