语义UI下拉菜单无法正常工作

Question

I want to make a multiple select search dropdown using Semantic UI, I already use bootstrap and if I use the entire Semantic theme it will destroy the bootstrap I already have in my project, so what I did is I included just the dropdown files (there is a seperate download on the Semantic website).

The problem is that the dropdown-only version is alot different than the semantic version (see links below).

I really don't want to use all of Semantic since it just won't work for me but I find it a bit odd that the standalone dropdown files don't match with the examples, am I missing a file?

<select class="ui fluid search dropdown" multiple="">
  <option value="">State</option>

Answer 1

Yes, you have to include other related files so that your dropdown looks like in Semantic UI. They are search.css and js, label.css and js, icon.css

Additionally you need some body specific css:

body {

    font-family: Lato,'Helvetica Neue',Arial,Helvetica,sans-serif;
    font-size: 14px;
    line-height: 1.4285em;
    color: rgba(0,0,0,.87);

}
