| /** | |
| * @file | |
| * Provide a javascript based dropdown menu. | |
| * | |
| * An example are the dropdown settings in the panels ui, like for adding | |
| * new panes. | |
| * | |
| * The dropdown menu will show up as a clickable link; when clicked, | |
| * a small menu will slide down beneath it, showing the list of links. | |
| * | |
| * The dropdown will stay open until either the user has moved the mouse | |
| * away from the box for > .5 seconds, or can be immediately closed by | |
| * clicking the link again. The code is smart enough that if the mouse | |
| * moves away and then back within the .5 second window, it will not | |
| * re-close. | |
| * | |
| * Multiple dropdowns can be placed per page. | |
| * | |
| * If the user does not have javascript enabled, the link will not appear, | |
| * and instead by default the list of links will appear as a normal inline | |
| * list. | |
| * | |
| * The menu is heavily styled by default, and to make it look different | |
| * will require a little bit of CSS. You can apply your own class to the | |
| * dropdown to help ensure that your CSS can override the dropdown's CSS. | |
| * | |
| * In particular, the text, link, background and border colors may need to | |
| * be changed. Please see dropdown.css for information about the existing | |
| * styling. | |
