i am building plugin for my multisite, so i need to be able to select some blog from the blogs list, and then get the blog id to use this id in another function.
the best solution will be using Autocomplete for users and sites field, the same wordpress using in Network admin.
the question is how i can use the same field in my plugin?
after i have start searching for solution i have found this topic on wordpress: https://core.trac.wordpress.org/attachment/ticket/19810/19810.21.patch
but i still did not realize how to use this in my plugin.
