sortable, sortable-item will be available as global custom attributes.
To get started you need to bind the sortable, sortable-item attributes in conjunction with the repeat attribute.
<ul oa-sortable="items.bind: items">
<li repeat.for="item of items" oa-sortable-item="item.bind: item"></li>
</ul>
This will enable the plugin to keep track of and move around the items.
If the sortable
custom attribute is in an area that is scrollable you have to bind either a selector
or an Element
or document
:
<!-- Other bindings omitted -->
<div oa-sortable="scroll.bind: '.page-host'">
</div>
Default scroll='document'
so it can auto scroll when needed. If you want you may even do a manual scroll when it's auto scrolling or combine them by first auto scrolling then manual scrolling and it should still behave as intended. If you are not happy with the sensitivity or scroll speed for the auto scroll you can set it with below bindings:
<!-- Other bindings omitted -->
<div oa-sortable="scroll-sensitivity.bind: 20; scroll-speed.bind: 20">
</div>
Default scrollSpeed=10
- how many pixels it will scroll for each frame
Default scrollSensitivity=10
- how many pixels from the scroll
bounding threshold until it starts auto scrolling.
If you have a vertical or horizontal list you can lock the sortable axis movement with:
<!-- Other bindings omitted -->
<!-- Lock to horizontal movement -->
<div oa-sortable="axis: 'x'">
</div>
<!-- Lock to vertical movement -->
<div oa-sortable="axis: 'y'">
</div>
Default axis=3
- sets the allowed axis movement. Which is both horizontal and vertical movement.
To make sure that the dragging of a sortable item always is on top of other elements make sure to bind:
<!-- Other bindings omitted -->
<div oa-sortable="drag-z-index.bind: 120">
</div>
Default dragZIndex=1
- z-index of the dragging sortable item.
To be able to have a sortable where you might be editing the sortable items you can control this by:
<!-- Other bindings omitted -->
<div oa-sortable="disallowed-drag-selectors.bind: 'DIV'">
</div>
Default disallowedDragTagNames=['INPUT', 'SELECT', 'TEXTAREA']
- element tags that disallows start dragging.
<!-- Other bindings omitted -->
<div oa-sortable="allowed-drag-selector.bind: '.handle'">
</div>
or
<!-- Other bindings omitted -->
<div oa-sortable="allowed-drag-selectors.bind: ['.handle1', '.handle2]">
</div>
If that is insufficient:
<!-- Other bindings omitted -->
<div oa-sortable="allow-drag.call: allowDrag($event);">
</div>
Default allowDrag
@bindable public allowDrag = ({ event }: { event: Event, item: SortableItem }) => {
const target = (event.target as HTMLElement);
if (this.allowedDragSelector &&
!matchesSelector(target, this.allowedDragSelector)) {
return false;
}
if (this.allowedDragSelectors.length &&
this.allowedDragSelectors.filter((selector) => matchesSelector(target, selector)).length === 0) {
return false;
}
if (this.disallowedDragSelectors.filter((selector) => matchesSelector(target, selector)).length !== 0) {
return false;
}
if (target.isContentEditable) {
return false;
}
return true;
}
where $event
has event
and item
properties.
event
- the native DOM event
item
- the sortable-item
view-model
<!-- Other bindings omitted -->
<div oa-sortable="on-stop.call: onStop()">
</div>
<!-- Other bindings omitted -->
<div oa-sortable-item="type-flag.bind: 1">
</div>
You can use an abstract type flag to enable/disable moving between lists. This is useful for more advanced scenarios i.e multi nested sortables. Checkout the advanced demo for more insight.
