Use a shortcode to define a drop-down form field, and shortcodes to define blocks of content that will be displayed when a specific entry is selected.
To add a content dropdown to a post, you can either select the Content Dropdown icon from the TinyMCE editor, or enter the shortcodes manually.
[dropdown name="controlName" class="customClassName"] - both `name` and `class` are optional; `name` will default to `dropdown-content`
nameis used to identify which content sections are targetted by this dropdown; if there is only one dropdown on a page, it is optional; if there are multiple dropdowns on a page, each will need a unique name
classcan be a space-separated list of class names, or just a single class name
[dropdown-option]shortcodes may be inside this shortcode
[dropdown-option value=”someValue”] – the
valuefield is technically optional, but is required if this option is meant to make a content block visible

Copy and paste the following content to see the plugin in action
[dropdown-option value=”option1″]First option[/dropdown-option]
[dropdown-option value=”option2″]Second Option[/dropdown-option]
[dropdown-content value=”option1″]Content for the first option.[/dropdown-content]
[dropdown-content value=”option2″]Content for the second option.[/dropdown-content]
Those were all using the default values from the plugin. Let’s change it up a bit.
[dropdown-option value=”option1″]The First[/dropdown-option]
[dropdown-option value=”option2″ default=true]The Second[/dropdown-option]
[dropdown-option value=”option3″]The Third[/dropdown-option]
You’ll notice below that the second option will be displayed by default for you.
[dropdown-content value=”option1″]Some different content for the second first option.[/dropdown-content]
[dropdown-content value=”option2″]Some different content for the second second option.[/dropdown-content]
[dropdown-content value=”option3″]Some different content for the second third option.[/dropdown-content]

- How do I override your CSS?
Only three classes are used:
dropdowncontent-dropdownfor the dropdown control itself and has no default styling,
dropdowncontent-contentwhich has a single rule (
display:none;) for content blocks, and the
dropdowncontent-content-selectedclass which has a single rule (
display:inherit;) for selected content blocks. Feel free to override those styles however you like in your own stylesheets.
- Can I style the dropdown box itself?
Absolutely! It is a normal
dropdowncontent-dropdownclass, any custom class you add to the shortcode, or the field name (which defaults to
dropdown-contentbut can be modified by the shortcode).
- What kind of content can be in the content blocks?
Anything! By default, though, since the blocks are given
dropdowncontent-contentclass and will fire in this order:
dropdown-content:unselectwill fire when a dropdown option is unselected and
$(this)will refer to the previously selected content block; the previous
namefields can be found with
dropdown-content:selectwill fire when a dropdown option is selected, and
$(this)will refer to the newly selected content block; the current
namefields can be found with
