Title: Cannot select subcategory field in entity
ThreadText: # Cannot select subcategory field in entity
  
  (Asked by: username_0 on 2015-09-03)
  
  I have a Structure section `fruit` with a single entry type `fruit`.
  
  I also have a Category `fruitType` with 2 levels:
  
  * Citrus
    + Orange
    + Lemon
    + Lime
  * Melons
    + Watermelon
    + Honeydew
  
  The entry type `fruit` has a Category field for `fruitType`.
  
  If I select a level 2 category for the `fruitType` field, say `Orange`:
  
  [![Category Selection](https://i.sstatic.net/fjMbi.png)](https://i.sstatic.net/fjMbi.png)
  
  Craft CMS dismisses the category selection pop-up and the parent category is shown instead, in this case `Citrus`.
  
  [![Resulting Category](https://i.sstatic.net/GiyDD.png)](https://i.sstatic.net/GiyDD.png)
  
  From the browser's network inspector, I noticed that a POST request to `/admin/actions/elements/getCategoriesInputHtml` with the following form data:
  
  ```
  categoryIds[]:893
  locale:en_us
  id:fields-fruitCategory
  name:fields[fruitCategory]
  limit:1
  selectionLabel:Category
  
  ```
  
  However, the response from the server is:
  
  ```
  {"html":"<input type=\"hidden\" name=\"fields[fruitCategory]\" value=\"\">\n\n<div id=\"fields-fruitCategory\" class=\"categoriesfield\">\n\t<ul class=\"elements structure\">\n\t\t\t\t\t<li id=\"fields-fruitCategory-category-887\">\n\t\t\t\t\t\t\t\t<div class=\"row\" style=\"margin-left: -0px; padding-left: 0px;\"><div class=\"element removable\" data-id=\"887\" data-locale=\"en_us\" data-status=\"enabled\" data-label=\"Faculty\" data-url=\"http:\/\/craft.local\/fruit\/citrus\" data-level=\"1\" data-editable><input type=\"hidden\" name=\"fields[fruitCategory][]\" value=\"887\"><a class=\"delete icon\" title=\"Remove\"><\/a> <div class=\"label\"><span class=\"status enabled\"><\/span><span class=\"title\">Citrus<\/span><\/div><\/div><\/div>\n\n\t\t\t\t\t\t\t<\/li>\n\t\t\t<\/ul>\n\n\t<div class=\"btn add icon dashed\">Category<\/div>\n<\/div>\n\n"}
  
  ```
  
  Based on the response and what's rendered in the interface, Citrus is shown and not Orange, despite Orange being selected.

  Unlike structured entries, when you relate a category to another element, its ancestors are also included in the relation. Due to [the way Craft looks up these ancestors when relating the selected categories, to enforce this behaviour](http://buildwithcraft.com/classreference/services/CategoriesService#fillGapsInCategoryIds-detail), the ancestors are added to the relation *before* the one you selected, and it looks like you're limiting that Categories field to **1**, so *only* the parent is being added.
  
  Try setting the limit on that Categories field to **2**.
