FileTree

FileTree(__namedParameters): Element

Defined in: src/components/controls/FileTree/FileTree.tsx:98

A file-system-flavored specialization of TreeView: it maps a file/folder model onto the tree, auto-assigns file-type icons (by extension) and open/closed folder glyphs, and adds drag-and-drop import of OS files onto a folder (or the root). Expansion, selection, keyboard navigation, and sizing are inherited from TreeView unchanged.
