Question: I need to create a dropdown menu with "**posts** from a custom post type" as option.

This dropdown will be placed as custom meta box.

For example, I want all posts with the custom type "Video" as option in the select.

```
<select>
   <option>post title n°1<option>
   <option>post title n°2<option>
   ....
</select>

```

Thanks

Answer: 
```
wp_dropdown_pages(array('post_type'=>'video'));

```

Since my last answer was considered more of a question. I'll answer with more of an answer. You could use the Magic Fields plugin 2 (note the 2 because that is a different but improved plugin). You can choose a 'related type' field from the admin boxes they offer. Of course you still can excavate how it's done in this plugin if you want to create this function yourself, but at least there is somebody who figured it out.
