11
+ == Description ==
12
+
13
+ Order your pages (and any hierarchical custom post types) with simple drag and drop on the page (or custom type) management / list screen.
14
+
15
+ The following video is from an earlier build (0.7) that has been refined.
16
+
17
+ [youtube http://www.youtube.com/watch?v=wWEVW78VF30]
18
+
19
+ Simply drag and drop the page into your desired position! It's that simple. No new admin menus pages, no dedicated clunky user interfaces. Just drag and drop on the page list screen.
20
+
21
+ To facilitate the menu order management on sites with many pages, the plug-in also adds a new drop down filter allowing you to customize the paging (pages per page) on the page admin screen. Your last choice will even be saved whenever you return (on a user to user basis and post type by post type basis)!
22
+
23
+ The plug-in is "capabilities smart" - only users with the ability to edit others' pages (i.e. editors and administrators) will be able to reorder pages.
24
+
25
+ Integrated help is included! Just click the "help" tab toward the top right of the screen; the help is below the standard help for the screen.
26
+
27
+ Note that this plug-in only allows drag and drop resort within the same branch in the page tree / hierarchy for a given page. You can instantly change the hierarchy by using the Quick Edit feature built into WordPress and changing the "Parent" option. This may be addressed in the future, but the intention is to avoid confusion about "where" you're trying to put the page. For example, if you move a page after another page's last child, are you trying to make it a child of the other page, or position it after the other page? Ideas are welcome.
28
+
29
+ This plug-in is being released as a "beta" in the Google sense. There are no known issues, but it requires much more comprehensive testing with custom post types and environments with large number of pages before we can label it "1.0". You must have JavaScript enabled for this plug-in to work.
30
+
31
+ Please note that the plug-in is currently only minimally compatible with Internet Explorer 7 and earlier, due to limitations within those browsers.
32
+
33
+
34
+ == Installation ==
35
+
36
+ 1. Install easily with the WordPress plugin control panel or manually download the plugin and upload the extracted
37
+ folder to the `/wp-content/plugins/` directory
38
+ 1. Activate the plugin through the 'Plugins' menu in WordPress
39
+ 1. Start dragging and dropping by going to the "Page" admin menu (or custom post type equivalent)!
40
+
41
+

Murray Consulting</a>) that allows you to order pages and other hierarchical post types with drag and drop.</p>
92
+
93
+ <p>To reposition an item, simply drag and drop the row by "clicking and holding" it anywhere (outside of the links and form controls) and moving it to its new position.</p>
94
+
95
+ <p>If you have a large number of pages, it may be helpful to adjust the new "items per page" filter located above the table and before the filter button.</p>
96
+
97
+ <p>To keep things relatively simple, the current version only allows you to reposition items within their current tree / hierarchy (next to pages with the same parent). If you want to move an item into or out of a different part of the page tree, use the "quick edit" feature to change the parent.</p>
