title: Implement Multi Select feature (Long press/Hold and select) in Ionic
body: <p>I am working on an Ionic project having a list. I want a multi-select feature <strong>just like the hold and select feature in android gallery</strong>, so that upon long press checkboxes appear in front of list items, enabling me to select more than one item.</p>
  
  <p>Any suggestions on how to implement that? I am <strong>not looking for GalleryView</strong> feature but just long press and select feature, just like it.</p>
  
  <p>Is it possible without creating actual checkboxes? Or do I need to create checkboxes and implement the on-hold event?</p>
  
  <p><strong>Note:</strong> For those who are confusing whether I want to implement android gallery feature, please pay attention! I DO NOT want to implement android gallery feature here. I only want to implement a MULTI-SELECT feature on simple list in the same way we select multiple images on long press in android gallery, or even take an example of selecting multiple contacts in contact list, etc.</p>
