npm install @cn-ui/sortableThe SortableList is a drag-and-drop sortable list component built with SolidJS and Sortable.js. It allows users to rearrange items within the list through drag-and-drop interactions, and it integrates seamlessly with reactive data, ensuring that both the data and the view are kept in sync.
- Reactive: Utilizes atomic state management provided by @cn-ui/reactive.
- Configurable: Supports all options from Sortable.js.
- Easy Integration: Provides context sharing for unifying data sources across multiple components.
- Automatic Handling: Automatically adds the necessary data-id attribute to each list item, simplifying the developer's task.
Ensure your project has the following dependencies installed:
``bash`
npm install @cn-ui/reactive solid-js sortablejs
First, import the SortableList component into your component file:
`javascript`
import { SortableList, SortableShared } from "@cn-ui/sortable";
`jsx`
import { atom } from "@cn-ui/reactive";
import { SortableList, SortableShared } from "@cn-ui/sortable";
export default () => {
const data = atom([
{
id: "223232",
label: "info",
},
{
id: "111",
label: "info1",
},
{
id: "222",
label: "info2",
},
]);
return (
getId={(item) => {
return item.label;
}}
>
{(item) => {
return ;
}}
);
};
- model (required): A reactive array containing the list items.
- options: An object with configuration options passed to Sortable.js.
- children (required): A function that renders the list items, receiving the current item and its index as parameters.
- fallback: Content to be displayed when the list is empty.
- getId: A function to extract the unique identifier from the list item; defaults to using item.id.
- disabled: A reactive boolean to control whether the sorting functionality is enabled or not.
- setData: A function to set the data transfer object and the element being dragged.
- onSorted: A callback function that is triggered after the sort operation, providing the updated list of items.
You can also use the SortableShared context to share data and options among multiple SortableList instances. This is useful when you have multiple lists that need to share the same data source or configuration.
#### Example with Shared Context
`tsx`
import { atom, computed, resource } from "@cn-ui/reactive";
import { SortableList, SortableShared } from "@cn-ui/sortable";
export default () => {
const data = resource<{ data: { id: string; label: string }[] }>(
async () =>
Mock.mock({
"data|10": [
{
id: "@id",
label: "@cname",
},
],
}),
{ initValue: { data: [] } },
);
const modelLeft = computed(() => data().data.slice(0, 5));
const modelRight = computed(() => data().data.slice(5));
return (
<>
options={{
group: "common",
}}
>
{(item) => {
return {item.label};
}}
options={{
group: "common",
}}
>
{(item) => {
return {item.label};
}}
{JSON.stringify(modelLeft().map((i) => i.label))}
{JSON.stringify(modelRight().map((i) => i.label))}
);
};
- You can customize the appearance of the SortableList by passing additional props such as class, style, and event handlers via the props object.RefreshData
- The function can be used to manually refresh the data if needed, although it's typically called automatically after a sort operation.
- Ensure that each item in the v-model array has a unique id property, or provide a custom getId function to avoid conflicts.disabled
- The prop can be used to conditionally enable or disable the sorting functionality based on your application's logic.
By following these guidelines, you should be able to integrate and utilize the SortableList` component effectively in your SolidJS applications.
