svelte-sortable-items

svelte-sortable-items is a svelte/sveltekit package to create sortable drag-and-drop items. This package allows you to relate a javascript array to sortable HTML elements.

WHY ANOTHER SVELTE PACKAGE FOR SORTING?

svelte-sorting-items differs from other svelte sorting packages by not committing to a specific html structure (like "ul/li" lists). Furthermore, it promotes sorting from the child elements only, instead of sorting the children of a parent element. This allows a non-opinionated structure/styling and, consequently, the ordering of more flexible structures, such as the lines of a table for example.

FEATURES

• NON-OPINIONATED STYLING.
• NON-OPINIONATED HTML STRUCTURE.
• WORKS ON MOBILE. YOU JUST HAVE TO LOAD svelte-drag-drop-touch
• TYPESCRIPT SUPPORT.
