<p>In multiple mode, select2 doesn't allow the same tag to be selected more than once. This default behavior can be overridden by implementing the <code>hideSelectionFromResult</code> function:</p>

<p>By default, the selected item is visible in the result list in single mode and hidden in multi-select mode.
This behavior can be overridden by implementing the <code>hideSelectionFromResult</code> function.</p>
<p>For instance, in the case of a single select box it can be used to hide the selected item from the result list:</p>
<pre class="prettyprint">
function hideSelectedItem(selectedObject){
return true;
}
$("#e1").select2({
hideSelectionFromResult: hideSelectedItem
})
</pre>
<p>More complex behavior can be achieved by reading the text of the selected item:</p>
<pre class="prettyprint">
function hideAlaskaFromResult(selectedObject){
return selectedObject.data("select2-data").text == "Alaska" ? true : false;
}
$("#e1").select2({
hideSelectionFromResult: hideAlaskaFromResult
})
</pre>
<p class="alert alert-info">The return value of <code>hideSelectionFromResult</code> is a boolean. It returns undefined if it is not implemented.</p>
