Answers.Text: Thanks for the Response Brandon. This is about half way there.
  
  The client has requested the editing be a two way street, meaning that they be able to add and remove associated recipes from the ingredients edit screen.
  
  This is beneficial because say they were to add a new ingredient, they can quickly associate it with all applicable recipes rather than having to open each individual recipe and add it there.

Body: <p>So, for example:</p>
  
  <p>Say I have two sections:</p>
  
  <pre><code>- Recipes
  - Ingredients
  </code></pre>
  
  <p>Recipes can have many ingredients. Ingredients can have many recipes.</p>
  
  <p>If I'm editing a Recipe, I can edit the ingredients. This updates the relationship so that when I edit ingredients it can show the associated recipes (and they are editable from the ingredients as well).</p>
  
  <p>Is this possible with Craft?</p>
  
  <p>Thanks!</p>
  
  <p>====== EDIT ======</p>
  
  <p>Just to make this more clear. What I'm trying to do is create a Many to Many relationship between two Sections of Entries so there is an association between the two that works both ways.</p>
  
  <p>Another example of this would be if you have a User with many Roles. I can manage which Users belong to which Roles from the Roles section, and/or I could manage which Roles a User belongs to from the Users section.</p>

Title: Is it possible to create a fieldtype that creates a many to many relationship between two entry sections?
ThreadText: # Is it possible to create a fieldtype that creates a many to many relationship between two entry sections?
  
  (Asked by: username_0 on 2014-07-01)
  
  So, for example:
  
  Say I have two sections:
  
  ```
  - Recipes
  - Ingredients
  
  ```
  
  Recipes can have many ingredients. Ingredients can have many recipes.
  
  If I'm editing a Recipe, I can edit the ingredients. This updates the relationship so that when I edit ingredients it can show the associated recipes (and they are editable from the ingredients as well).
  
  Is this possible with Craft?
  
  Thanks!

  You can assign ingredients to recipes using the built-in [Entries](http://buildwithcraft.com/docs/entries-fields) field type.
  
  Then, to view which recipes an ingredient is used on, check out the [Introvert](https://github.com/iainurquhart/craft_introvert) plugin. It gives you a new field type that can be used to simply show reverse relationships, also providing links to edit those other entries.
