Code a WordPress function

I have a requirement for a plugin that I am creating. I will provide the basic plugin for you to work from. See attached: [login to view URL] When the job is complete and working, I will take what you have done and use it in my actual final plugin. - Activate the attached plugin. - Go to Tools -> Test plugin and you will see an input field. What Needs To Be Done. 1) The user needs to be able to type into the field and select posts or page titles as that are suggested as they type. See attached: [login to view URL] 2) The title should also be able to be removed from the field by clicking the x next to it. 3) When the user clicks the SAVE button, obviously the field should show the post titles that were selected, and the user should be able to add or remove more. At the moment the plugin already saves whatever is in the field when you click SAVE. Code Quality. Please keep your code clean and legible. Add comments so that everything can be understood when passed onto another developer. DO NOT add a bunch of bloated, unnecessary dependencies, obscure frameworks or anything like that. The preference is that everything is done with WordPress functions and methodologies. But it's OK to use PHP and jQuery of course. Please, only experienced WordPress coders should apply for this job. About Me. I have been coding for WordPress for 10+ years exclusively (I've built several popular premium themes and plugins) and am now experimenting with outsourcing small jobs like this so that I can focus on bigger projects. One Final Thing. If you apply for this job within just seconds of it being published, I will know that you have not read this far (or read anything about it at all) and you will not be awarded the job. I would expect anyone serious would read the job requirements before applying for it. Thanks in advance.
