title: Getting HTML to linebreak in django admin's display
body: <p>I have this as my django display</p>
  
  <p><img src="https://i.imgur.com/9TinDNS.png?1" alt=""></p>
  
  <p>The code for doing this is:</p>
  
  <pre><code>class PurchaseOrder(models.Model):
      product = models.ManyToManyField('Product', null =True)
  
      def get_products(self):
          return "\n".join([p.products for p in self.product.all()])
  
  class Product(models.Model):
      products = models.CharField(max_length=256, null =True)
  
      def __unicode__(self):
           return self.products
  </code></pre>
  
  <p>views.py:</p>
  
  <pre><code>class PurchaseOrderAdmin(admin.ModelAdmin):
     fields = ['product']
     list_display = ('get_products')
  </code></pre>
  
  <p>So I've attempted to do this:</p>
  
  <pre><code>from django.utils.html import format_html
  
   def get_products(self):
      return format_html(" &lt;p&gt; &lt;/p&gt;").join([p.products for p in self.product.all()])
  </code></pre>
  
  <p>however, it's still not returning it in HTML. Or rather, the way I want it in the image</p>
