Added uiSelectFooter directive for bottom of list

[csebold]

My humble attempt to contribute a footer directive for the bottom of the dropdown menu

I would be a fan if this was merged. My project has several cases where we need a footer, and at the moment we are hacking up a solution involving two sets of dom nodes inside of ui-select-choices and turn them on/off if it is the last element.

This is a feature of Select2, but I don't see it on ui-select's roadmap. I'd love to see this rolled in, though. If there's something I can do to make the code fit better, I'm willing to make it happen.

A header would be helpful as well... Same basic idea.

[ghost]

any idea on if/when this will be merged and released?

@csebold I think that this might be good, but I see some trouble on each theme:

Bootstrap

• footer is shown when the dropdown is closed
• footer is shown on top of the dropdown

Selectize

• footer is shown when the dropdown is closed
• footer isn't shown when dropdown is open
  
  

Select2

You mention:

This is a feature of Select2, but I don't see it on ui-select's roadmap

But I dont see this on select2. I wanted to see if there were some select2 css clases to keep same style as right now seems like without any padding or default style

anything more about having a ui-select-footer / ui-select-header? I would really like this.

This would be very helpful for me as well. For instance, for providing a "toolbar" for creating new entities in lookup fields that use this combo-box.

My version of adding header and footer is at PR #1323

Adds:
ui-select-header
ui-select-footer

Closing in favour of #1323 when it works.
