This behaviour controls the look of this 'dragged' Element. - -Demo: https://jsbin.com/sibiput/edit?html,css,js,output - - ---- - - -#### `fallbackTolerance` option -Emulates the native drag threshold. Specify in pixels how far the mouse should move before it's considered as a drag. -Useful if the items are also clickable like in a list of links. - -When the user clicks inside a sortable element, it's not uncommon for your hand to move a little between the time you press and the time you release. -Dragging only starts if you move the pointer past a certain tolerance, so that you don't accidentally start dragging every time you click. - -3 to 5 are probably good values. - - ---- - - -#### `dragoverBubble` option -If set to `true`, the dragover event will bubble to parent sortables. Works on both fallback and native dragover event. -By default, it is false, but Sortable will only stop bubbling the event once the element has been inserted into a parent Sortable, or *can* be inserted into a parent Sortable, but isn't at that specific time (due to animation, etc). - -Since 1.8.0, you will probably want to leave this option as false. Before 1.8.0, it may need to be `true` for nested sortables to work. - - ---- - - -#### `removeCloneOnHide` option -If set to `false`, the clone is hidden by having it's CSS `display` property set to `none`. -By default, this option is `true`, meaning Sortable will remove the cloned element from the DOM when it is supposed to be hidden. - - --- - -#### `emptyInsertThreshold` option -The distance (in pixels) the mouse must be from an empty sortable while dragging for the drag element to be inserted into that sortable. Defaults to `5`.

In order to do this, there must be a `defaults` object on the initialized plugin. This can be set in the plugin's prototype, or during the initialization of the plugin (when the `el` is available). For example: ```js function myPlugin(sortable, el, options) { - this.defaults = { - color: el.style.backgroundColor - }; + this.defaults = { + color: el.style.backgroundColor, + }; } Sortable.mount(myPlugin); ``` - ## Plugin Events ### Context + The events will be fired in the context of their own parent object (ie. context is not changed), however the plugin instance's Sortable instance is available under `this.sortable`.

However, it sometimes may be desirable for a plugin to listen in on an event from Sortables in which it is not enabled on. This is possible with global events. For an event to be global, simply add the suffix 'Global' to the event's name (casing matters) (eg. `dragStartGlobal`). Please note that your plugin must be initialized on any Sortable from which it expects to recieve events, and that includes global events. In other words, you will want to keep the `initializeByDefault` option as it's default `true` value if your plugin needs to recieve events from Sortables it is not enabled on. Please also note that if both normal and global event handlers are set, the global event handler will always be fired before the regular one. ### Event Object + An object with the following properties is passed as an argument to each plugin event when it is fired. #### Properties: @@ -119,7 +124,7 @@ An object with the following properties is passed as an argument to each plugin `dragStarted: Boolean` — Boolean indicating whether or not the dragStart event has fired -`putSortable: Sortable|undefined` — The element that dragEl is dragged into from it's root, otherwise undefined +`putSortable: Sortable|undefined` — The element that dragEl is dragged into from it's root, otherwise undefined `activeSortable: Sortable` — The active Sortable instance @@ -133,7 +138,6 @@ An object with the following properties is passed as an argument to each plugin `newDraggableIndex: Number` — The new index of dragEl, only counting draggable elements - #### Methods: `cloneNowHidden()` — Function to be called if the plugin has hidden the clone @@ -146,8 +150,8 @@ An object with the following properties is passed as an argument to each plugin `dispatchSortableEvent(eventName: String)` — Function that can be used to emit an event on the current sortable while sorting, with all usual event properties set (eg. indexes, rootEl, cloneEl, originalEvent, etc.). - ### DragOverEvent Object + This event is passed to dragover events, and extends the normal event object. #### Properties: @@ -168,7 +172,6 @@ This event is passed to dragover events, and extends the normal event object. `target: HTMLElement` — The sortable item that is being dragged over - #### Methods: `onMove(target: HTMLElement, after: Boolean): Boolean|Number` — Calls the `onMove` function the user specified in the options diff --git a/docs/sortable-options.md b/docs/sortable-options.md new file mode 100644 index 000000000..3e2e2b3b6 --- /dev/null +++ b/docs/sortable-options.md @@ -0,0 +1,234 @@ +# Sortable Options + +todo: on[Event] options.
