Dropkick exclude "option selected" value within drop down

[benlevydesign]

Dropkick inside modal window doesn't consider height of element and open in the direction with enough space. You can see it happen here

Also, Is it possible to exclude the "option selected" value from within the drop down.
For example this: ( In my example below $priority is <option value="None">None</option> )

<div class="flex">
    <div class="flexbox flex">Edit location priority:</div>
    <div class="formsize">
        <div class="form-select">
        <select class="priority toggle-spinner" name="priority[1]">
        <option selected value="<?php echo $priority ?>"><?php echo $priority?></option>
        <option value="None">None</option>
        <option value="Low">Low</option>
        <option value="Medium">Medium</option>
        <option value="High">High</option>
        </select>
    </div>
    </div>
</div>

Would look like this instead:

<div class="flex">
    <div class="flexbox flex">Edit location priority:</div>
    <div class="formsize">
        <div class="form-select">
        <select class="priority toggle-spinner" name="priority[1]">
        <option selected value="<?php echo $priority ?>"><?php echo $priority?></option>
        <option value="Low">Low</option>
        <option value="Medium">Medium</option>
        <option value="High">High</option>
        </select>
    </div>
    </div>
</div>

Thanks,
Ben!
