title: Orchard - Taxonomy Field no longer displays all possible values
body: <p>I recently upgraded a client's Orchard CMS installation from 1.9.x to 1.10.2. Everything went smoothly. However, we are missing some functionality that was previously available.</p>
  
  <p>Before, to select a topic (Taxonomy Field), I would click in the Topics field and a box with all available topics would appear. I would then click on the desired topic. To add more topics, I just had to repeat.</p>
  
  <p>Now, however, clicking on the field does nothing. A cursor appears in the box, but no topic window appears...</p>
  
  <p>...until I start typing. But here’s the catch. If I type an ‘a’  only topic names that contain an ‘a’ are shown. Any topic that does not contain an ‘a’ is not shown.</p>
  
  <p>If I know the topic I want, no problem. I simply start typing it, and the topics list will filter itself accordingly and I just need to click the topic to add. Repeat as needed.</p>
  
  <p>The problem with this is that if I don’t know the topic the I want, there’s no way to easily know what topics are available. And if I wasn’t aware that the list was filtered based on the letter I typed, I might assume that a certain topic wasn’t entered into our system.</p>
  
  <p>Is it possible to go back to the old way the Taxonomy Field was set up?</p>
  
  <p>Thanks.</p>
