title: selectize keep seeing all available options when setting value with php
body: <p>We are using selectize to load some options from some provider php classes, and it works perfectly when creating a new item.</p>
  <p>When editing an existing one, we use php to set the value and the text of the element, and then when loading the form, one has to delete the text from the input to be able to see the other options. Is there anyway to see that the value is selected, but when clicking all options show up? The same way as in the creation, you select an option, it is selected, you click on the select, you view all options...</p>
