+Creates a dropdown list of non-hierarchical taxonomies as an alternative to the term (tag) cloud. Formerly known as Tag Dropdown Widget.
+
+== Description ==
+
+Creates dropdown lists of non-hierarchical taxonomies (such as `post tags`) as an alternative to term (tag) clouds. Multiple widgets can be used, each with its own set of options.
+
+Numerous formatting options are provided, including maximum numbers of terms, term order, truncating of term names, and more.
+
+Using the `taxonomy_dropdown_widget` function, users can generate dropdowns for use outside of the included widget.
+
+This plugin was formerly known as the `Tag Dropdown Widget`. It was completely rewritten for version 2.0.
+
+== Installation ==
+
+1. Upload taxonomy-dropdown-widget.php to /wp-content/plugins/.
+2. Activate plugin through the WordPress Plugins menu.
+3. Activate widget from the Appearance > Widgets menu in WordPress.
+4. Set display options from the widget's administration panel.
+
+== Frequently Asked Questions ==
+
+= What happened to the Tag Dropdown Widget plugin? =
+
+Since I first released this plugin in November 2009, WordPress introduced custom taxonomies and, as more-fully discussed below, saw a new widgets API overtake its predecessor. As part of the widgets-API-related rewrite, I expanded the plugin to support non-hierarchical custom taxonomies, which necessitated a new name for the plugin.
+
+= Why did you rewrite the plugin? =
+
+When I first wrote the Tag Dropdown Widget plugin (and it's sister Tag List Widget), WordPress was amidst a change in how widgets were managed. I decided to utilize the old widget methods to ensure the greatest compatibility at the time. In the nearly two years since I released version 1.0, the new widget system has been widely adopted, putting this plugin at a disadvantage. So, I rewrote the plugin to use the new widget API and added support for non-hierarchical taxonomies other than just post tags.
+
+= I upgraded to version 2.0 and all of my widgets disappeared. What happened? =
+
+As discussed above, WordPress' widget system has changed drastically since I first released this plugin. To facilitate multiple uses of the same widget while allowing each to maintain its own set of options, the manner for storing widget options changed. As a result, there is no practical way to transition a widget's options from version 1.7 to 2.0.
+
+= If my theme does not support widgets, or I would like to include the dropdown outside of the sidebar, can I still use the plugin? =
+
+Insert the function `<?php if( function_exists( 'taxonomy_dropdown_widget' ) ) echo taxonomy_dropdown_widget( $args, $id ); ?>` where the dropdown should appear, specifying `$args` as an array of arguments and, optionally, `$id` as a string uniquely identifying this dropdown.
+
+* taxonomy - slug of taxonomy for dropdown. Defaults to `post_tag`.
+* select_name - name of first (default) option in the dropdown. Defaults to `Select Tag`.
+* max_name_length - integer representing maximum length of term name to display. Set to `0` to show full names. Defaults to `0`.
+* cutoff - string indicating that a term name has been cutoff based on the `max_name_length` setting. Defaults to an ellipsis (`&hellip;`).
+* limit - integer specifying maximum number of terms to retrieve. Set to `0` for no limit. Defaults to `0`.
+* orderby - either `name` to order by term name or `count` to order by the number of posts associated with the given term. Defaults to `name`.
+* order - either `ASC` for ascending order or `DESC` for descending order. Defaults to `ASC`.
+* threshold - integer specifying the minimum number of posts to which a term must be assigned to be included in the dropdown. Set to `0` for now threshold. Defaults to `0`.
+* incexc - `include` or `exclude` to either include or exclude the terms whose IDs are included in `incexc_ids`. By default, this restriction is not enabled.
+* incexc_ids - comma-separated list of term IDs to either include or exclude based on the `incexc` setting.
+* hide_empty - set to `false` to include in the dropdown any terms that haven't been assigned to any objects (i.e. unused tags). Defaults to `true`.
+* post_counts - set to `true` to include post counts after term names. Defaults to `false`.
+
+= Why are the makeTagDropdown(), TDW_direct(), and generateTagDropdown() functions deprecated? =
+
+Version 2.0 represents a complete rewrite of the original Tag Dropdown Widget plugin. As part of the rewrite, all prior functions for generating tag dropdowns were deprecated, or marked as obsolete, because they are unable to access the full complement of features introduced in version 2.0. While the functions still exist, their capabilities are extremely limited and they should not be replaced with `taxonomy_dropdown_widget()`.
+
+= Where do I obtain a term's ID for use with the inclusion or exclusion options? =
+
+Term IDs can be obtained in a variety of ways. The easiest is to visit the taxonomy term editor (Post Tags, found under Posts, for example) and, while hovering over the term's name, looking at your browser's status bar. At the very end of the address shown in the status bar, the term ID will follow the text "tag_ID."
+
+You can also obtain the term ID by clicking the edit link below any term's name in the Post Tags page. Next, look at your browser's address bar. At the very end of the address, the term ID will follow the text "tag_ID."
+
+= I'd like more control over the tags shown in the dropdown. Is this possible? =
+
+This plugin relies on WordPress' `get_terms` function (http://codex.wordpress.org/Function_Reference/get_terms). To modify the arguments passed to this function, use the `taxonomy_dropdown_widget_options` filter to specify any of the arguments discussed in the Codex page for `get_terms`.
+
+To make targeting a specific filter reference possible should you use multiple instances of the dropdown (multiple widgets, use of the `taxonomy_dropdown_widget` function, or some combination thereof), the filter provides a second argument, `$id`, that is either the numeric ID of the widget's instance or the string provided as the second argument to `taxonomy_dropdown_widget`.
